Afternoon all. Wondering who the hell sells decent oversize valves for a 9 port. Precision is the obvious one but they don't have a size that suits my application. My inlets are 1.68, 0.344, 4.504 and exhausts are 1.437.
Thanks all.

I used stainless Manley Buick v6 ones and then machined the heads down

I have used Pep-Pro. They are a really nice stainless valve, similar to Manley. Flow was up at least 1 CFM over std/EVL. .
