I have an XY with a 2V head, with a 350 holley. First thing with the holley, can it be tuned properly with any great advantage. since it's been installed had no problems but was wondering cause a mate told me of this guy who could tune the holley for us.... any worth???
second, I keep seem to blow manifold gaskets, blown like 3 in 6 months, any main reason for this, for is the guy who is replacing it doin a shit job???
