combo question

i wanna go with a MS4 cam for the summer, not sure on the heads, i was leaning towards the ported ls6 heads, or some ported ls1 heads. i dont wanna go with an aftermarket head, any advise on which out of the two heads will make more power for my MS4 cam.

ported ls6 243's or 799's will outflow any ported ls1 head any day.

As long as you leave the valve size stock and leave the deck stock you will not have to flycut with the MS4. Our stg 1.0 LS6s would be the heads I would recommend you take a look at if you don't want to flycut the pistons.
