And a set of stock 906's will flow what? Like 260? I should be able to get 300 cfm out of my 906's for a grand, shouldn't I???? My heads have been gasket matched and have a valve job already. My thinking is that I can spend an additional $1,000 and get close to the Eddys which would cost me $1500+. Yes, I could sell my 906's and almost make up the difference, yes the Eddys are much lighter, yes I could run a little higher compression... I know the benefits. But if the power is near the same (minus the weight savings) - for THIS car I'd like to keep the original heads. Basically, whatever a grand gets me is where I'll end up I think.
