M&A vs Champion Alum heads????

[Black Car]

I know M&A design isn't as new as Champion but....
Looking for information from people who has run the M&A as a street driven full weight car.
Good as well as bad.

Anyone has flow data on the M&A??

If anyone has used M&A & gone to Champions what differences did you see?

What spark plugs are used in the M&A?

TIA
Gary

I am using M&A heads and my is driven on the street.I like the heads and have not had the leaking problem that everbody has had with the Champion heads.Neal Stewart has a set of the latest heads from champion and he says they don't leak and he likes them.TA Performance is developing a new set that will be ready soon I understand that they are the last one's that M@A develpoed but never marketed I do know that Kenny Duttweiler had a hand in develpoing them these might be worth waiting for.

Thanks Reg,
Talked to TA yesterday & the head production schedule changed to maybe spring time.
Just looking for information because my engine is waiting on heads.

Read the GN-1 R head thread in Stage II forum. It will probably help a little.

M&A's will crack, if you push them. So far the R heads are not having problems.

Black Car,

What heads did you decide on?
