He is going 2650,,,, GOTTA be file fit and gapped,, with an acre or more of ring land,,, too!!! Especially at his power levels!!!! My personal choice would be the Manley's for this application!!!I should have asked about rings also--file to fit, or Total Seal Gapless??
Short answer is nope.Are you using the smaller LS3 (11mm) head studs or the larger ls9 (12mm) size? Are the LS9 ARP studs available? If so upgrade the stud size and your back in the game. Hate to see you down still after you have waited this long.
