Building a new 505 With Callies / Mopar Performance Block

SMCARNUT said
I have a set of 240's here for a friends 505 street motor build and my 270's both sets are tight. Very little if any side clearance. Hopefully the shims will work if not both sets of heads will be back to the machine shop.

I think I better just give mine a check again too. I'm not sure I really remember doing that.
