Can anyone tell me the correct installed height and seat pressure for stock 88 350 heads with the factory roller cam?

Thanks.

 

Seat pressure should be at least 120 psi, and is dictated by installed height. Measure cam lift and rocker ratio to find valve lift and then compare this to coil bind height and installed height. A good number to shoot for 100 thou coil bind clearance. When assembling your head try to match the weakest springs with the shortest valves to balance the valve train.
