Default lq9 stage 3 heads on a 5.3

i know the heads will work. but will the valves clear the cylinder walls if the valves are 2.08 and 1.60 valves. ? i know the heads are WAY overkill. but im planning on running alot of nitrous ! and when i blow this motor i can use these heads on my 6.0

i believe stage 3 317 heads are for 4 inch bores only so they wont work on a 4.8,5.3,5.7..

Those large chambers would kill your compression. Generally people want extra compression if they're running nitrous. If you destroy your engine, chances are your heads will get trashed as well.
