You can use your 327 stuff in a 350 block but you'll need to get a set of spacer main bearings------
I haven't seen why they won't work with my own eyes, going by what my engine builder told me. This motor as with the 327 came in a box completely apart. Heads have been milled/cut at least once. I'll have to look into it further and see what and the why's of it. I think its valve clearance issue vice the actual head itself. I wish I had the confidence to build it my self but its been 30 yrs since my last engine build.
