Default ls3 top end questions

Hey guys,

I plan to do a Ls3 top end on a 6.0 Ls2...It is a 402 stroker with 2cc pistons.

Right now my plans are to go nitrous.. I was wondering what valves to go with. I plan to do a 200-250shot..I plan on using stock ls1 rockers for the exhaust valves and obviously ls3 offset rockers for intake valves... Also with 660 or 675 springs.

Right now my compression is 12 to 1 ..i'm going with the ls3 top end with 70cc chambers to lower compression.

I was also wondering if there's going to be any clearance issues since the ls3 intake valve is so large.

I also was debating in going with prc ls3 heads but don't really want to spend that kind of coin right now.

Any help would be greatly appreciated!!
