Follow the recommendations from the cam manufacturer.
Could be--valve not closing completely
The 92 did not have a roller cam in it.
A Chevy 305 with a roller cam will have MORE power than a 305 with a flat tappet cam if both are installed in the same engine. The horsepower of any 305 depends on what all is done to the engine. Changing from flat tappet to roller will gain some. There are other ways to increase horsepower and there are other ways to increase torque.
The intake valve is bigger.
It is a hydraulic camshaft, Not a roller cam. Chevy did not start using roller cams until late 1995
The Intimidator 305

YES it does and it is a roller cam and hydraulic lifters.
intimidator 305 which is 305 feet and drop 300 feet going at a upgraded max speed of 90mph
302 or 305? 302s never did. 305(5liter) in about 90 or 92. I first saw factory roller cams on the 87's with one piece rear main seal and raised-rail heads.
