Different head gaskets, thicknesses, gasket coatings, clamping loads, had the heads O-ringed(final engine was a culmination of the three.). 8 head gasket sets, 2 blocks, and 8 connecting rods later I called it quits July of ‘17; when I lost another head gasket set after the dyno in may. Finally broke down, and invested in a closed deck block. Wasn’t until I took a stone to my old deck surface that I realized the there indeed are very noticeable high and low spots that form from cylinder expansions that are happening under high boost pressures. At the end of the day I’m telling you, one memeber to another, I don’t care who says what or what they think they know; your car WILL blow head gaskets over 800whp if you choose not to support the cylinder from shifting in some shape or form. 1Life the dynosty built haltech car did it at 820whp which is why he had his engine rebuilt, and purposefully turned back to 780-790.

FYI Charles is not looking to push Justin’s built car without some sort of cylinder reinforcement(whether that be dowels, inserts, or a block fill time will tell); they are merely using Justin’s car as a test bed to run the GTR head bolts which are currently being used on R35s well into the 12-1300whp realm. Not too bad considering the set of 16 can be bought for less that $100.
