finally got around to ordering my heads, got AFR 230 small bore heads being built right now to top of my forged 347 midframe turbo build. and got the sad news the my LS9 gaskets wont work with them. soo i need a gasket with a 4.135 bore..

what gasket should i be looking at for this kinda heartbroken that i can run my ls9s and will be selling them off now.

 

TT 347 with AFR 225's here. I run the ls9 gasket. Best choice imo. The cometics look like junk in comparison.

coming right from Tony Mamo.. ls9 gaskets WONT work the bore is too small

guess i should of read this a bit better cometics are the way to go i guess

 

Straight from Tony would be him posting...lol.

I might beleive he said they aren't the best choice. If he said the won't work, he is just wrong. Many people are running them with these heads with zero issues. I owned both the cometics and the ls9's at the same time. I returned the cometics.

 

no it was in a pm from him that he stated they wont work. texas speed also stated in that thread they had issues on first start up..

 

I really don't see how it would be an issue on a small bore motor. No issues here.

 

congrats im not goin to chance it though.. specially when the guy that works there says dont do it
