1) Disconnect PCV hose, necessary electrical connections and spark plug wires to access valve cover. Remove nuts, seal washers, valve cover and gasket. 2) Rotate crankshaft clockwise so cylinder No. 1 is at TDC on compression stroke. Cylinder No. 1 is front cylinder at timing belt end of engine. Ensure timing mark on crankshaft pulley aligns with “0″ mark on timing belt cover. 3) Ensure valve lifters on cylinder No. 1 are loose and valve lifters on cylinder No. 4 are tight. If conditions are not as described, rotate crankshaft clockwise one complete revolution (360 degrees). 4) Using feeler gauge, measure valve clearance between valve lifter and camshaft on intake valves of cylinders No. 1 and 2, and exhaust valves of cylinders No. 1 and 3. Record valve clearance. Rotate crankshaft clockwise one complete revolution (360 degrees). 5) Measure and record valve clearance on intake valves of cylinders No. 3 and 4, and exhaust valves of cylinders No. 2 and 4. Ensure valve clearance is within specification. See VALVE CLEARANCE SPECIFICATIONS table. VALVE CLEARANCE SPECIFICATIONS TABLE (1) Application In. (mm) Exhaust Valve ………….. .012-.016 (.31-.41) Intake Valve …………… .006-.010 (.15-.25) (1) – Adjust valve clearance with engine cold. 6) If valve clearance requires adjustment, rotate camshaft so lobe on valve to be adjusted is facing upward, away from valve lifter. Position notch area on valve lifter toward inside of cylinder head. DO NOT align notch area with camshaft. Use Valve Clearance Adjuster (SST 09248-55040) to adjust valve clearance. 7) Using SST “A” of valve clearance adjuster, push downward on valve lifter. Place SST “B” between camshaft and valve lifter. See Fig. 2. Ensure enough clearance exists for adjusting shim removal. Remove SST “A”.

Using measured clearance and adjusting shim thickness, select proper replacement adjusting shim. See Figs. 4 and 5. 9) Install replacement adjusting shim. Recheck valve clearance. Apply sealant at indicated valve cover sealing areas on cylinder head. See Fig. 3. 10) Using NEW gasket, install valve cover and sealing washers. Install and tighten nuts to specification. See TORQUE SPECIFICATIONS. To install remaining components, reverse removal procedure. NEW SHIM THICKNESS TAB

Tests/Procedures: 1. Use a scanner and command the air pump on with the engine running at idle. Check if the O2 sensors go lean. 2. If the O2 sensor does not go lean on one bank, see if the check valve at the exhaust manifold is stuck closed, not allowing air into the manifold.

INSTALLATION PROCEDURE 1. Disconnect battery negative cable. 2. Disconnect throttle body from Mass Air Flow Sensor boot and disconnect all lines from throttle body (linkage, water, vacuum, etc.). 3. Remove linkage attachments from plenum and move out of the way. Disconnect plenum from runners and remove (it is not necessary to remove throttle body from plenum). You may need to loosen lower runner bolts in order to free plenum. 4. Remove runners from baseplate and loosen, but do not remove the fuel rails. 5. Trial fit your new intake runners prior to final installation on your vehicle. This way you can get a “feel”for what goes where and why. NOTE: Because of varying O.E.M. fuel line routing, some material may need to be removed from the runners in order to clear the fuel lines. Check for clearance before installing onto engine. 6. Thoroughly clean the flange surfaces of the plenum, runners, and baseplate and remove any remaining gasket material. Use rags or paper towels in the open ports to make sure your intake system is kept free of all foreign objects (i.e., dirt, gasket material, etc.). 7. Place runners into position on the baseplate making sure to use the proper runner/gasket on the proper side and start bolts. 8. Tighten down fuel rails and place plenum into position. Start bolts, but do not tighten (make sure proper gaskets are used). 9. Align plenum and runners and tighten all runner and plenum bolts. 10. Reconnect all connections and linkage to the throttle body and reconnect the throttle body to Mass Air Flow Sensor boot. If clearance is a problem, it may be necessary to discard the original steel hard line which runs from the O.E.M. baseplate to a rubber hose connecting to the charcoal canister and replace with a rubber hose. On the passenger’s side of the engine, discard the original hard line (if so equipped) which ran from the valve cover vent to the throttle body and replace with 3/8″ rubber hose if necessary for clearance. 11. Check and top off any lost coolant, reconnect battery, and start engine and run briefly, monitoring the “check engine”light. Turn off engine and check installation for any leaks or abnormalities

Chevrolet Aluminum Cylinder Heads INSTALLATION INSTRUCTIONS

download
Before final installation of the cylinder heads, several things need to be checked to assure proper engine operation: 1. Piston to valve clearance – Minimum intake valve clearance should be .080″. Minimum exhaust valve clearance should be .100″. The point of minimum intake valve to piston clearance will usually occur somewhere between 5 and 15º ATDC during valve overlap. The point of minimum exhaust valve to piston clearance will usually occur 15º to 5º BTDC during valve overlap. Re-machining of the piston top eyebrows may be required with some pistons. 2. Proper lifter adjustment and rocker geometry – Check Lifter pre-load. Check clearance of push rod to guideplate. Rocker geometry should be checked making sure that the contact point of the roller remains properly on the valve tip and does not roll off the edge. Visual inspection of the rockers, valve springs, retainers, and pushrods should be made to ensure that none of these components come into improper contact with each other. If problems with valve train geometry occur, simple changes such as pushrod length may have to be made. OTHER ASSEMBLY TIPS When installing the sparkplugs and exhaust headers, be sure to use a high temperature anti-seize compound on the threads to reduce the possibility of thread damage in the future. Do not exceed a torque of 25 ft./lbs. on the intake manifold bolts and lubricate the bolt threads prior to assembly. If pushrod to cylinder head contact is a problem, loosen rocker studs and re-position guideplate as needed for clearance. INSTALLATION: Installation is the same as for original equipment cylinder heads. Consult service manual for specific procedures, if necessary. For 350 and smaller engines, use Fel-Pro head gasket #1003. #1003 has a flattened steel O-ring around each bore and will provide an excellent, long lasting seal. However, it will compress the aluminum and you must use #1003 for subsequent gasket changes to get a good seal. For 400 c.i.d. small blocks, use Fel-Pro #1014. YOU MUST DRILL “STEAM HOLES” IN CYLINDER HEADS FOR 400 ENGINES (see Figure 2). Be sure that the surface of the block and the surface of the head are thoroughly cleaned to remove any oily film before installation. Use alcohol or lacquer thinner on a lint-free rag to clean. Apply Loctite PST or suitable thread sealer to head bolt threads. Torque to 65 ft./lbs. in three steps (30-50-65) following the factory tightening sequence (see Figure 1). A re-torque is recommended after initial start-up and cool-down (allow 2-3 hours for adequate cooling)
