HIGH FLOWING PORTED J HEADS

We are putting a smaller exhaust valve in my W5 heads so that we can use a larger intake valve.


YEEEEEEEEEEEEEEEEEEEEEES! Just make sure you have probably 15-18 or maybe even 20 more degrees of exhaust duration and it will kick some ***. If you want you can PM me your bore, stroke, rod ratio, compression ratio and where you want to make peak torque and HP and I will run my math on it and I'll let you know what I get.

If (that's a BIG IF) I can fit a 1.500 in there with no steeper than a 52 degree exhaust seat then I will. I'd rather do a 50 but I might not be able to go that small and still get an nice valve job on it. Then I should be able to go 2.150 on the intake.
