I am sorry but you have a set of dished pistons in the bottom end. If you were to use the 781 heads you would have a compression ratio of 7.487. With this setup you will need to use a RV cam. Something like X4 254H. You will have good low end and mid-range power. The engine would have around 369 hp @ 4500 rpms and 510 lbs torque @ 2500 rpms. This will be fine for shows but not the track. BTW it would be your best interest to sell all the COMP .550/292 camshaft parts.
