Sometimes studs and increased torque can cause distortion of the upper cylinder walls, and that has to be compensated for by machining. Because of this, we prefer to use stock bolts unless the engine is a high boost, forced induction build.
Howard places the cylinder head down on the block.
Howard lubricates the spot faced areas on the head that the bolt head spins against. This helps to give a more accurate torque reading when tightening the bolts.
Howard then torques down the bolts in three steps, with the final step being to a given angle to set the stretch of the bolt. This gives a very even clamping for the head gasket and does not distort the top of the block out of design limits.
With the CNC-ported intakes, you can really see the straight shot to the intake valves and the combustion chamber. You can almost see the entire back face of the valve. With the intakes being straighter and more direct with porting, flow is improving.
Next, Howard installs the Ford Motorsports camshafts, the billet gear Ford Motorsports heavy duty oil pump, the variable timing gears, timing chains, and tensioners.
Howard now installs the front cover.
