which stroker to build?

Went with heads from
MRL Performance.also a balanced stroker kit. His roller lifters. Solid roller cam. Studs. Wind age tray. Etc. mike hooked me up. A great guy. Very helpful. And a fellow abodies only member. He said for sure the combo is gonna make 600-630 hp on 91 premium fuel. Can't wait to get this beast running and hope to afford a dyno day.
