Inliners International Forums General Discussion Hi Performance Chevrolet 261 build and head questions

This 261 block had a lot issues and if I had to do it again another block might have been cheaper.Bad main bearing cap,line honing,big overbore added 600 bucks to the cost.
Now I'm assembling the engine and I noticed the 6 top rings do not match,3 of one type,three of another type.The rings were supplied by Ross with their pistons,Hastings Plasma moly. Just more stuff to deal with.
