What's the rest of the spec? 46's would be better than the 42's

not sure yet, defo silvertop 2.0,ported and polished head work , cams either newman ph3 or piper 285 (witch ever gives best gains)
bottom end either standard with arp bolts or steel rods hi comp pistons. im looking to build 210 plus bhp without silly budget.
