INDY/RHS Head Flow charts are here.
Hello Guys, I usually post and look around in the Circle Track area but thought some of you would be intrested in seeing these numbers.
Let me know if I can help. Allen here is what I have. This is on a sales brochure I received from Indy Cylinder head. ALL NUMBERS ARE UN PORTED. Intake Exhaust 80.7 @ .100 75.6 @ .100 134.5 @ .200 135.4 @ .200 189.8 @ .300 174.8 @ .300 235.6 @ .400 193.7 @ .400 250.5 @ .450 196.8 @ .450 263.1 @ .500 198.4 @ .500 266.7 @ .550 198.4 @ .550 267.9 @ .600 196.8 @ .600 4.030 bore, 8mm stems 2.02 1.625 valves |

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.

why dont you do as I did??
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 Allen moparallen1@yahoo.com |

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 |
