Re: Sanderson Header Owners
I know Sanderson claims that. They have thick flange....IMHO I would and do always use a gasket, Felpro but do not have Sanderson headers
If your heads are dead nuts perfect and aluminum (read not cast iron), go for it...but I would use a gasket
with that said my 67 327 stock manifolds did not have gaskets and never leaked. YMMV
