Is anyone familiar with Kauffman racing? Looking at purchasing their
D port aluminum head for my 455 build. I have read they have very small intake and exhaust ports but I'm not sure can anyone chime in and let me know, or would I be better off purchasing round port Edelbrock heads?

Just an FYI… I was told by my engine builder that the edelbrock heads need work right out of the box. Very inconsistent machining…..ie valves being too tight, guides not put in properly.

Most require work out of the box, they don't know what the builder wants. They just supply basic cores, or at best a very general setup that still needs redoing as doesn't suit. Porting and machine work for the builder to select.

We made right at 600 HP with a set of KRE 290 CFM heads.Great heads IMO.Tom

Dave at SD performance opened them from 260 to 290.I think you can now buy them from KRE at 310?Friend just put a set on his 383-350 69 fired bird engine.Tom
