heads OR 383 for a DD
2002 z28 m6, stock 241 heads, 100 (soon to be 150) wet n2o
Car is a DD, looking to make around 450ish rwhp, be "streetable", and have decent low end power
Will be doing forged rods and pistons and a Cam (with springs ect) regardless
Question is would it be better to a 383 crank for the extra torque, and I believe you can run a bigger cam with the extra displacement,
or
Upgrade heads to 2.5 5.3's or 243's, but keep the stock crank?

^^But he said that it has forged internals, so I'm thinking that the 150 shot is relatively safe on the shortblock that the car has now. I would personally go with a set of heads and get some more untapped power out of the stock displacement setup
