S38
Shanon,
The air intake ports of the S38/M6 cylinder head are similar in shape to those of the M30 head. The problem is the method of bolting the manifolds to the M6 cylinder head. The M6 throttle bodies bolt to the cylinder head via 9 studs in the cylinder head - each of the three throttle bodies has 3 holes for the mouting studs. The Weber manifolds that I have seen are configured for the 12 studs on the M30 head. As if I don't have enough aggravation, I am working on an adaptor plate that would allow the M6 throttle bodies to be mounted to an M30 cylinder head.
Hope this helps,
Peter A
