Highest flowing sbm heads?
How is the Indy head flow? Ether head?
not sure what to believe in flow numbers you see around, but a local guy I race with has been 9.50’s with them with a glide and his car is a bit over 3000, and I know David Dean who I think posts on here once in a while has been over 120 in the 1/8 with them.
they used to make( don’t think they do anymore) a raised port 245cc head. I have seen a set. Very hard to get sealed up with intake.
problem is, they are leak prone, like W5 heads
i would think the -1 heads probably have 750 horse potential.
Have heard Vic Bloomer is playing around with the Indy head, not sure what that will result in regards offering them for sale. Would be an interesting development
