Multiple repair sleeves on big bore Dart Big M BBC

[SupStk]

Also curious how this will turn out. A buddy has a 4.625" Dart Big M that I refused to do. Appeared two head bolt holes would be too close to the sleeve. Figured there would be a good chance for cracking or distortion when torque plating.

Think normal sleeving practice of sitting the bottom on a 90 degree ledge would prevent slippage.

I just like the top flange better
