Maybe have TSP port your 799's. If I were that close to them, I would get a motor from em.

You put those heads on a 421ci and they will knock it down to a 383ci. 799's will choke the hell out of that engine. L92 heads are cheap and flow awesome.

My friends 422ci with a Fast 90/90 made 535 RWHP...can't tremember what heads though. With a cam that was in the mid 230's duration too. So you can make plenty of power.
