P-51 vs sr-71

506 cubic inch engine for truck puller. 4.400 bore, 4.160 stroke. 14:1 compression, Mafia intake, .800 ish lift solid roller, 1250 dominator. Engine will need to turn 8000 rpm.
Between the p-51 and sr-71 which should make more steam?

I’d be looking at the sr-71.
My need to talk with Kaase about having slightly smaller valves installed for valve clearance and shrouding reasons.

SR-71 without a doubt. I have a set on a 572 that now has 19 1/8th mile passes on it. I have no remorse in my purchase of the SR-71 heads. I wanted a no bullshit package that would make great power without breaking the bank. This is the first set of bbf heads that I have owned that make great power from the starting line to the finish line. I have raced d3's,dove,eddy's,tfs streets, a460, and now the Kaase SR-71.
