Spring pressure is a function of the cam. Rockers are good to go 2 threads showing on bottom at correct lash of the the adjuster and pushrods to fit. Check for spring clearance to rocker. If I am remembering correctly.
Well, it's been a while but also, there's been progress!
I've got the bottom end balanced and mounted with the Egge pistons. I bought them straight from Egge but later found that Hughes have them at a lower price!
Anyway, Thanks for all the input! I've also just decided what cam to use. It'll be a Lunati solid flat tappet. 235/243 @0.050, 110 LSA, 525/546 lift.
