I have the same heads with manley 2.25 intake and 1.94 exhaust valves I also had the heads reworked for 1.73 ratio b.b. chevy roller rockers from comp cam with crane hardened push rods, guide plates and a 292 comp cam you may want to keep an eye on your valve to piston clearance with with this set up. I went with stock style trw forged pistons but had the heads c/c'd for 9.5:1 compression. this is a great set up, sure made the engine breathe better and still use pump gas. i did upgrade a while back to some scj exhaust manifolds and this really livened things up. good luck

i use arp studs and prefer harland sharp rockers, since he originally desighned the roller rocker, studs about $30.00 and rockers around $205.00 through summit. make sure to check pushrod length, i had to go with scj length,8.650 for correct geometry.
