Lots more issues with the "new" Navarro's than what's apparent, including cooling hole misalignment?

Do a search, I checked these out very closely for a recent blown build here?

Thanks, Gary in N.Y.

P.S. Had words with H&H back then will NOT use or sell them here no matter what! Here's a few shots, with your short stroke and assuming they are also 80cc heads be a bit tough on the final C.R.
