Highest flowing sbm heads?

No I wondered what the bloomers cost. For the Victors 2045 is what I was told, but I was also told they aren't sure how they will come. Maybe valves and springs, which springs? They really werent sure but said we can get them set up for whatever I'm doing. They aren't even solid on the price. It's an educated guess right now until they come in.
Oh! Sorry….

If you can find out the spring rates to compare to the cam you want to run recommend spring that manufacturers suggest, you may have a match within a few scant pounds, if not, order the head bare with valves and proceed from there.
