I have the same set of heads and i got them because i heard good things about them. They changed the name of them to Roush 200's but i think its the same head. Mine are still in the box so you'll probably know before me how they work.
Mine are going on a 351 stroker (372) long rod motor, N/A.
At this time i have no intention of doing anything other than polishing the combustion chambers and the exhust ports. That could change later though. You'll probably finish before me, so post and let me know how they work for you, that way you're doing all the R&D and I won't have to make a bunch of dumb mistakes
As for the cam I'd call comp or whoever and tell em what you got and what you need it to do, they are usually good about working out a good combo for you.
