Looks like the exhaust port hits a brick wall after 400 lift. The int/exh ratio at 400 is .82 and is .75 at 500 lift. So, they might be tricky to cam for.

Oops. I read over your "unported" disclaimer too fast.

I called them, spoke to Sam there, he MAILED me the brochure I am listing numbers from. You are on several websites asking about the heads and seeming to doubt what people are saying. It is fairly easy to satisfy yourself. Do as I did, Call, speak to Sam, and hopefully all your questions are answered.

If I can help you in any way please send me a message.
Thanx

seem to doubt what people are saying??? you are the only one that has posted numbers... The only reason I have the littlest of doubt is because they havent listed anything on their site like they have with other heads. But I will call if they tell me the numbers you give me I will back you up.


ps On their site it says they come with the 1.920 valve

I think they are waiting for a major event to announce the heads to the public. I think it will be at the Mopar Nats. The heads are machined from the foundry with 1.92 valves, exactly like the heads they are replacing. I also think that is so they can be advertised like others (EQ) as a true bolt on. Avenger29 says that his machinest was impressed with them. Like I said the numbers I am quoting are on a flier I received in the mail from Indy Cylinder Head. After speaking with them, post what you hear.
