Welded the 16 extra lugs on to my Resto block to help hold down the Indy 360-2 heads. Used the head as a template using a drill sleeve in the extra head bolt holes to line them up perfectly...got 3/8 ARP studs going in them....used stainless mig wire and Argon/helium to keep from cracking.....hope it works...and helps.

Don't try this with roller lifters.....I am using Smith machine composite solid flat-tappets and I ground out just enough material for them to sneak by.
