alright i have a cammed 5.3 with stock 706 heads and i plan on trading my heads for my friend's Dart pro series I heads,
I believe 706's have 61ish cc chambers and I'm pretty sure his have 62 cc chambers
My question, Is it worth it to do the swap and trade a small bit of compression for better flow? I dont really feel like waiting to have these heads milled, so they go on as is.
BTW, Im staying N/A and I'm putting a 100-150 shot on it soon, and im almost sure the intake runners on the Dart heads are 225cc maybe not?
my mods are
220 cam
lt's
boltons
small stall, gears
