Head/Engine Combination help!
BTW i also have Lid, LS6 intake, Mac mid-length headers, ORYpipe, Borla exhaust, 6-speed, spec 3 clutch and flywheel, 10 bolt 3.42's. Dynoed 425 RWHP.
I was thinking about getting a set of ported LS6 heads, what should I look for to match my block and cam like chamber volume etc?
What numbers should I expect to the rear?
