How much more power will I get with Bigger heads I have TEA 1.5 heads worked a little more and an LS6 intake with ported TB. If I went to a Fast 90/90 with AFR 205 heads, what should I gain in HP?

The 5.3 heads with the smaller chamber make similar power to the AFR heads at 66cc. I would think you would have to mill the AFR heads to 59-61cc to pick up a solid 10-15 RWHP. The TFS heads when milled to 61cc would yeild about 20-25 RWHP and would yeild more piston to valve clearance then you have now. A Fast 90/90 will pick you up 20 RWHP right now!
