I have a 370 with a 4.030 bore in desperate need of some new heads. I am leaning towards the patriot stage 3 LS6s with 2.08/1.60 valves. Will these valves work well with my set-up? Going to a tsp 100mm maf and lid combo when I do heads.
TIA.

Those are good sized valves for a 4.03 bore. That's what most people use.

Using the 52% of the bore rule they will work. You don't want to go any larger.
