how much will my pushrod size change? story is I got a forged 370 with -15cc diamond pistons it had 243 heads stock size head gaskets with comp 918s and stock rockers I pulled the heads and seen the pushrods where the regular 7.400 question is when I switch my 243s and throw on my 317s with the same comp 918s but harland sharp 1.7 lifters and I change my head gaskets to a compressed thickness of .045 how much will my pushrod size change?
I assume you mean Hardland Sharp rockers and that these are the roller rockers. If you, first step is setting geometry. Don't simply bolt them in. Once geometry is set on the rockers (by setting the rocker height) you will have to measure for the pushrod length.
