I'm considering going with a smaller cam, like the Comp Cams XE-250/260, XE-252/252, or XE-260/260. I'd probably just buy the whole kit, springs, lifters, chain and all if I don't go with remanufactured heads.
Also, just realized pistons are first cheap for these. The KB domes are cheap and supposed to reduce combustion chamber volume by -6.00 cc, so that seems to be another viable way to get back some lost cranking pressure from a longer duration cam.
