LS9 VS LS7 Gasket
I just placed my order for a set of the AFR mongoose heads and they are recommending a Cometic 4.160 Bore Size on their website... I had already placed my order for a set of LS9 gaskets that are showing to be a 4.100" Bore sizing.. Do I need to return these for a LS7 Gasket 4.150'' bore size? Or should i order a set of 4.160'' cometic gaskets..
Additional info if needed. 4.070' Bore, 3.622' Stroke, 6.125' Rod Length, -3.2cc Flat-Top, 1.304' CH Piston - Wiesco -3.2cc Flat-top (#10-K398X7) AFR Mongoose 260cc Heads (Recommend 4.160'') Last edited by Nighthawk89; 11-28-2018 at 10:41 PM. |

Wait til the heads arrive, and measure across the chamber
All the GM gaskets are good gaskets though |
