[Grumpy old man]

I.think your way off , your running it so advanced trying to track down another 50 horse power that's just not there , now what's up with the hot fuel filter ? I'd be chasing that issue first it just may become the cause of many of your issues . Back it down to basics and while your at it back up the timing and let it live until the engine you really want is ready . Nothing's worse than a blown engine with a ton of shiny parts sitting in the garage .
