    Was wondering in plugging the exhaust crossover holes on the two center exhaust ports is worth it since I’m using the SP3 intake, and that has no provisions for the crossover, and plugging the holes in the head would be a moot point o_O
    OOOOR plug ‘em anyway to reduce the turbulence and keep the hot exhaust from beating the crap outta the aluminum intake flange o_Oo_Oo_Oo_O

    I would plug them. If nothing else it keeps the carbon from building in there.
