Contact John Armstrong. He's your neighbor and he's the man.

Hasn't seen enough of these himself to say if one better than another.

You might contact Jimmy Bridges next week. Jimmy has a fair amount of experience with the big block heads.

If you flow tested 5 820 heads and 5 292/241 heads the 820 casting would have a better average. The 820 head also seems to respond better to modifications. The sort turn on the 820 exhaust is also raised more than the 292/241.

I can't remember, but the 820 always responds good when ported, the chamber is inefficient though.
