Spoke to Steve of SW Motorsport today, he has built H6 engines putting out 1100bhp not that I'm going any where near that level.
So first order the standard crank is ok for my plan, will keep my forged conrods maybe the pistons if I keep the car supercharged but will have to change pistons if going the turbo route to lower the cr. The block will be pinned.
Interestingly he said most head gasket failures are caused by movement of the head bolt thread in the block so will be investigating some new head studs with a finer thread than standard.
For the heads the exhaust valves will be changed for iconel ones with uprated springs.
He has seen oil usage like mine before when the bores were to coarse and wore the rings allowing the oil past and the valve stem oil seals are definitely suspect as well.
Covered some other stuff which I will get to later depending on what route of forced induction I use.
The first engine died after eating to much CAT
The second engine died of a broken piston
The third engine is in the car
The fourth engine is in the machine shop
