LS1 vs LS2 block head sealing
I'm planning a LS build possibly with a new LS2 block. It occurred to me that there is less material in the 4" bore LS2 block between the cylinders. I'm planing a max of 15 PSI with meth on gas. Compression approximately 10:1. Anyone with FI experience with these blocks feel that this reduced material is significant or am I trying to pick the fly crap out of the pepper with this minor difference?

LS2 block will easily be able to handle that...and then some...and then a bit more.
Although it staying at that low boost, maybe consider an LS3 for a few more cubes ?

Remember I concerned about sealing not structural integrity. I know the LS2 block can handle the stress of the 15 PSI but is the reduced material between the bores of any significance relative to sealing? That may be what you meant but just double checking.
