Nobody in their right mine is going to buy a 48 degree block, expensive rockers, pistons, and an intake to run a head that flows less than a ported Speedmaster head. They are pretty pathetic stock.
Agree, however…
There also available for a 59* block, so there’s that.
Price me an intake…
Rockers are the pricey deal.
On the SM head, what head exactly are you starting with and what are the before and after flow numbers?
Cost to have the SM heads ported.
NOT YOUR COST!
What is someone paying to have it done?
Below I see some good numbers in the as cast state.
When you ported the SM did the flow numbers exceed the W9?
Have you flowed a W9 on you bench?
