When you are done with the second valve. rotate the crank at least twice. and it has not been moved from its factory position. reinstall the head in the same manner as before so you can verify proper pushrod length and valvetrain geometry by following the procedure described in the Valvetrain G eometry Tech Info. Put a small amount of ARP moly lube on the tops of all washers once they are in place.G e ometry If you choose to use the stock cam in your engine. C arefully cut the clay in slices and look for the thinnest section of the valve impression. Torque the bolts in the three stages below.) B.-lbs. There are three different lengths of head bolts/studs. Once the checking procedures are done. This is done intentionally to regulate coolant flow. (Make sure the lifter is the same height as your original--you'll need it for checking valvetrain geometry later. you must follow this procedure to assure safe operating cle arances betwe en your pistons and valves: A. thick strips of modeling clay across the upper half of the piston. and valvetrain for the position you are checking (intake or exhaust). Place a solid mock-up lifter in the lifter bore of the valve that you'll be checking. Loctite Blue for studs). If you have an aftermarket cam or are reinstalling ANY cam (especially with a multi-keyway timing set). -lbs. For mechanical cams. turn the rocker arm adjusting nut 1/2 to 3/4 turn after zero lash. Adjust the exhaust rockers of cylinders 1. then the intake rockers of cylinders 1.-lbs.-lbs. With #1 piston at TD C on the exhaust stroke. In either case you can use the following adjustment order. you must get the correct lash specification from the cam maker. torque the studs to 55 ft. This is the easiest method since it requires only one turn of the crank. hardened pushrods into the pushrod holes. Step Two: 52 ft. If they are not. If you are using a hydraulic cam and no specs are available. 3. Do not use a gasket on the end rails. and 8. which is explained in the Prelubing the Valvetrain section. You're . 5. Be sure to coat the base threads of the rocker studs with the Permatex 3H to seal the threads. Intake Manifold Tips Apply a 1/4 in. 2.

Outline the water openings at the ends of the head with the Ultra Black to help prevent water leaks. but can be done if desired. Step Three: 70 ft. 4. to be safe. Leave the #1 piston at TD C on the compression stroke for the rest of the reassembly. Reassembling the Rest of the E ngine Install as many items as you can without putting the valve covers on.-lbs. you should have them milled flat. Go over once again at 70 ft. the leaking exhaust gas will burn out the gasket. Prelubing the Valvetrain You are now ready to prelube the valvetrain. This allows proper break-in of the valvetrain. This will make the valve covers sit higher--take this into account when reassembling accessories that mount on or cross over the valve covers.trying to pull the flange down evenly. Exhaust Leak Note: What sounds like a lifter tick is often an exhaust gas leak. 12. The best setting will depend on your particular engine combination and ambient conditions. After the engine has been run a few times. allow 2-4 hours of normal driving time before running the engine hard. the engine will start quickly. springs.

Break-In and Tuning After installing the valve covers. To ensure long life and trouble-free usage. to provide clearance for roller rocker arm poly locks. If they loosen up. Rule out exhaust leaks before tearing the intake off to replace the lifters. If you are also breaking in a new cam. Remember that you will have to use guideplates if you do not use the self-aligning rockers. It is a good idea to use an oil squirt can to get inside the valve spring and lube the valve stem and seal area. They both vary directly with rpm and sound alike. you will have to reduce the width of the baffle by squeezing it in the center until it clears.
