The engine is a smalll block chevy with dart shp 180 heads and a retro fit hydraulic roller camshaft. I used the felt tip marker on top of the valve method. I came up with 7.2 inches for the pushrod length using the adjustable pushrod. My question is do I have to add or subtract from this number to accomodate for the lash in the hydraulic roller lifter?

When the exhaust valve for a cylinder starts to open does this mean I am on the base circle of the cam for the intake valve? Thanks.

why don't you just watch for the intake valve to fully close?
