I know that on the description of these heads it says to only run a minimum of 4.030 bore. But will these not work on a LS2 403/404 with a 4.010 bore? Don't see why they wouldn't. The valves aren't any bigger than the patriot stage III's I ran in the past. Thanks guys.

Those you be perfect for your application you should have enough cubes to get good air velocity

Yeah I know they'll be awesome on the car. Just want to make sure they'll physically work with no valve interference?

They claim 4.030 for a reason(must be there chamber width). I know the valve will not hit anything.

You know this how?
Have you bolted a set on yourself?
What was your combo?
Interested...

Have NOT run that particular head myself, but I have used a 2.08 valve in a 3.900 bore and it was ok. AFR 225 383 deal.
