I think he meant he has a good set of heads

Response to cam selection

Correct me if I am wrong, but I don't think he plans 800 hp from his set up, but he has a set of takeoff heads from a race motor (which likely had a LOT more compression, cam and RPM) that made 800 hp

My opinion, I think your cam choice will be pretty rowdy and is likely too much cam for 9.5:1 compression. Not undrivable rowdy, but it's got tight centers and big lobes that are better suited for more compression IMHO if you choose to run it

FWIW, my 489 is at 10.7:1 and runs a lot less cam, it's pump gas friendly and is a blast on the street. I am not trying to talk you into less cam, but if you go with a cam around the specs you are talking about, you'll need more compression and even doing so, it'll still be street friendly
