damn, is that head junk now? What did FED say?

said they can fix it. if i wanted to keep doing what im doing or turn it up more, i need to swap to a different guides and iconel exhaust valves...better springs..

which at that point i was ready just to jump up to the big boy heads and repair these back to how they were (cheaply). their f-series heads come with upgraded springs and guides. so the only added costs would be for the different valves but they have a raised intake/exhaust runner which means i would have needed to find more room to go up with the intake. more money, more power, but i dont think i can find the extra height.

would have been easier just to starrt with a fresh set of heads, but they're on backorder/sold out for a few months basically. so sending mine in was the fastest option
