^what he said.
Without headers you are seriously hindering the additional flow those heads provide. I doubt anyone will have results on the combo you are looking for. Hell, if anyone actually does i'd be surprised if it makes close 400 rwhp.

I don't know if this is the case with the original poster but it's the reason I ran stock manifolds and an LS1 intake when I had ported heads.
When I finally did bolt headers and an LS6 intake on (1 3/4-1 7/8-3 1/2 collector) I picked up 7mph in the 1/4 with those two parts and some tuning.

Good call but you can get things done w/them on.
You don't pop and people can't see long tubes under the car. Also the car will still be quiet.

Nevermind, i just found that post, it was on stock exhaust manifolds. However, the before header numbers were 385. It was on LAPD's dyno. Those are damn sick numbers through the stock manifolds.
