I can't keep the heads on my iron block This iron block has had 3 sets of stud, 2 sets of heads, and been two 2 machine shops. There are a total of 5 head gaskets that have left us on the side of the road. This issue happened at all different power levels. The first 3x before I got it where close to 1000rwhp and two with me one time within the first 100miles at 5200rpm, 5lbs of boost, and 16 degrees of timing. The second time we had 15lbs and I held for 6 one gear blasts down the hwy before we ended on the side of the road. The block has been decked any ideas?

If stock GM MLS, I'd look at the LS9s or Cometics.
You might also want to consider O-ringing the block and going with Copper head gaskets at 1k rwhp. Hell, I think at that point, you might want to look at an aftermarket casting with a much thicker deck.

^ That would be ideal but maybe look into a LSA top end for that 370. Could probably just about break even after selling the Stage 2.5 243's and Intake and getting some CNC LSAs and equivalent intake depending on what your running.
Exactly what..
