Junkyard 360 LA Head Porting Questions

Like others say, go conservative. OEM crank and bottom end of the block won't live at 7,600. Even with W-2 heads on a 360, my old Challenger ran best around 6,800. Didn't see any difference at 7100, so why stress it. Higher compression will be hard on the bottom end too. Look around at proven combos. I ran low 11's with stock valve, unported LA-X heads at 3,540 lbs and under 11-1 flattops in my Dart Sport.
