Valve Adj Help Needed

[whosyurdaddy]

I have a SBC with a Crane roller cam #118411 (jegs) , track 1 heads , SRP 12:9/1 pistons and I need to adjust the valves but I can't find any specs . This motor has never been fired and PO thinks the adjustment should be 12int/18exh . I need some ideas

Bill, I have never seen any solid lifter or sollid roller camshaft with that much spread between the intake and exhaust lash. Most of the time, they are equal or + .002 exhaust.
Just my experience.

Bill, That makes sence now. Like picking seperate profiles from the CompCam book (one of my favorite reading materials).
