Tracey Scott. And unless the price is pretty good (in my favor), I'm going with AFR 205's. I sleep much better at night when I buy the right parts the first time

You only made 8whp more than my stock LS1 heads with your LS6 heads. I will note your tq is about 20 higher tho.

So is the MS3 cam better matched with the 5.3heads versus to the LS6 heads?? Seems like the MS3/ported 5.3 head combos are making the same rwhp as MS3/ported LS6 head combos but the MS3/ported 5.3 head combos are making 20-30rwtq.

The problem with the MS3 and LS6's is piston to valve clearance. That's why you don't see many of those combos!
