Port size?

[shaggy]

I tried to email these questions to info@championracingheads.com, but the message bounced back.

Can anybody help with this?

I have a couple questions concerning the ported iron and GN1 heads.

1) What are the dimensions (Height & Width) of the exhaust port openings? I'm in the process of building a naturally aspirated engine, for a buick skyhawk, and I want to make sure my headers have a large enough opening.

2) Are the prices listed on the website for assembled pairs? It appears that is the case for the GN1 heads, but it's not clear concerning the ported iron heads.

3) Could you possibly tell me the weight of an assembled iron & aluminum head?

Thank you

TTT

Law of averages says someone knows this info.

They are ported to a 1200 intake and a 1400 exhaust Fel-pro gasket. So get the #'s on those and you have it. Yes the irons are sold complete. I think an iron head weighs 25-30 lbs each complete. Thanks,Frank

Much appreciated

Thanks Frank!

I looked up the part number on net.
The answer is 1.15"x1.45".
