It's gonna be a stock block and stock type pistons, I'll probably have the head milled 0.100 so I'm guessing the CR will be about 9:1 or just a bit lower. Don't have the engine apart yet to measure anything.
Besides shooting for 9.5:1, I recommend the larger valves, the 225 is grossly under-valved. If the head recon is going to require new ones anyway, that's an automatic decision, that simple.
Even though the Intake-biased dual-pattern cams haven't proven out to "help", they won't hurt, that bumpstick should work fine. I also highly suggest stronger 3/8" pushrods, if they'll make it in the budget, get them.
