I bought these new several years ago. The project took a different direction and now these are left over.
PLEASE read carefully: after working in several automotive machine shops in my 46 years of wrenching, I got these and dis-assembled one to check it out. First, these heads are well designed, they feature heart shaped chambers, excellent port design, offset intake valve, and standard (raised) ports. I started by doing some bowl blending and blending of the CNC port edge machining. What I was not sure about was the Valves seem too long, and I think the intake seats need to be sized to the valves. I think they should be gone through by someone who works on these all the time. Setting these up takes experience if you want the valve train to survive. I am of the opinion, though they are an excellent design, they are assembled by people who don't know what they are doing and just put them together. These heads should make and easy 600-700 horse on a 512 stroker or other 500 inch Mopar. I can say that they did the homework when designing these, the chambers line up EXACTLY on the edge (like they should) of the cylinders on the .055 over 440 block I had them mocked up on. Send me a message, I can communicate any way you like.
