I have a set of AFR 195cc LT4 heads that were ported by GTP (stage 2)to 210cc. I was wondering if anyone could recommend an intake and exhaust gasket for these. I dont think GTP is in business anymore and afr wont recommend a gasket since they were ported by GTP.

 

I run LT4 intake gaskets that I have to open up for my runners.

On the exhaust side I use Mr. Gasket #5903, which is a good fit.

 

Just wondering what size intake valves you have in your 195s? I have the old 195s w/ 2.02 intakes, so I'm planning to have Lloyd Elliot work them over off-season and go to 2.05s.

I have not measured them but the guy i got them from said they were 2.08

 

From what I've heard, with the 2.05 valve upgrades you can reuse the original valve seats in the AFR 195s. However, with the 2.08s the seats will need to be replaced. Again, that is what I've heard, not for sure.

Also, did they retain the D-port design on the exhaust ports with your port work? For some reason, I’ve always liked the D-port exhausts and have Kooks headers with the D-port flange.

They are more of a square shape

 

I think the AFR 210s use a square exhaust port, rather than the Ds. Can you post some photos of your reworked 195s?
