LQ4 comp w 243 heads
LQ4 comp w 243 heads I am getting a 10.35:1 ratio with the 64cc chambers of the 243's. I am using GM stock LS3 gaskets ( 4.068" x .051" )and the heads have had a small cleanup pass on them just to make sure they are straight. Does this sound about right?
It was gonna originally be a boost build and the vendor I bought them and the arp studs from told me they hold well over 1000hp without issue. BTW, the setup in your sig is what Im trying to do with my dd.
are you sure they aren't LS9 gaskets? and ah okay. yeah my car did 11.43 at 119mph with 3.70 gears, yank 3600, TSP 1 7/8th headers, FAST 92mm Street heat stage 2 and bone stock 243's with no milling but they did have 4 bad exhaust valves that would not seal correctly. I'm doing a boost build now but your car should haul ***.. I would just switch to an LS2 gasket or a cometic .041 thick gasket
