It really depends on how well the heads flow, but even with a stock or near stock 906/452 head casting it should make 425hp/500tq unless something is wrong.

I wish I knew more about the heads, I will look to see what he did but I know they cost me almost $2000

Assuming a lot of course... but I would have to agree with Ron's estimate :2thumbs:...
Assuming the heads were cleaned up and touched up a bit, but not necessarily fully ported, that's going to be a pretty close estimate under normal test conditions.
