Are any aftermarket cast iron heads allowed in superstock c/s?

Re: ss/cs

I hear that Comp Cams is trying to get the okay on the RHS 14 degree.

ok sorry brain fart . i'm a chevy guy i forget there are other brands. i should have said any oem iron inline valve head with an oem casting number. my bad.

Re: ss/cs
 

what about an approved aftermarket casting that is legal for superstock ? like dart ?

Re: ss/cs
 

None allowed; the approved cylinder head for GM the Bowtie Vortec racing cylinder head. Randy and Michael Mans are very fast with the GM head.

I have been told the best Blue Oval head is the N351 or N352 10 Degree head

Re: ss/cs
 

The N351 is far superior than the N352.

No question early head is best for DR, fill the floor 3/8 inch and raise the roof the same amount it will be good!
