781 BB Heads, Info required please

[jacquesdean]

Its been a while since I've had any involvement with BB parts.
I require any info in these heads, I heard they were pretty good. I might be wrong.

Appreciate any help you can give me.

Thanks riptide, I was also wanting to know if they were a good head to use, do they flow well, what sort of HP can I expect, that sort of thing,

they are very sought after heads for oval port,put the big valves in them, port and polish and they will flow better than stock retangular port heads.they are the best street/strip heads without going after market. a friend of mine has a set and he's pushin 500 to 550 horse on a 454 with a mechanical L-88 cam he has it in a street/strip 68 chevelle high 11's or low 12's i can't remeber what it turned last time he took it to the strip.he's got it all tore apart getting tubbed and ladder bars, he kept going threw tires for some reason.
