318 build suggestions?

I'd go magnum heads and spend the money on a hydraulic roller cam personally...an honest 350-380 (maybe the mythical 400) should be doable with magnum heads that have some bowl work and hughes 1110 springs with valve guides cut for .550-.560 lift, an RPM air gap/air gap copy, 650ish cfm carb, and if flat tappet, I'd look to have bullet cams grind one with this lobe: HC272/336 272adv [email protected] [email protected] 0.3360 lobe lift (.537" lift with stock magnum 1.6 ratio rockers)...I'd have it ground on a 110 LSA and install it at like 106ICL because I'm not a fan of a lot of overlap that causes chop at idle.
