:lol: ....obsessed kind of limited with those heads and compression ratio...if it makes 500hp i'll be surprised...but will make up for it with torque...my guess maybe 400hp an 500ftlbs of torque...not too bad for a tow vehicle...all that tq will be down low which is good....

I thought you had rectangle heads on that??? I think it will be in the 540-550.
On a side note one of my old "stock" motors had some port work done to the 781 heads, 9.75:1, hydraulic camd and made 576 hp on Wheelers dyno....on 92 gas.

We just did a 496 with this same set up, dart 308 heads, engine made 555 hp and 615 torque with quick fuel 850.
Compression was 9.0:1 had flat tops.
Cam had just a little more duration, around 230 @50 but lift was only .510
