340 Hydraulic lock inspection update...

Dwayne Porter did my X heads and I’m pretty sure he can get everything you can out of them, but unless you are required to run a cast iron head or just want to run them. I’m not sure why you would have one done to match the other side. You would end up in a better position having a pair of CNC ported aluminum heads done. Without the ticking time bomb of other heads valves/springs/ect. I like Ferrea valves, in my experience they tend to bend when abused and not have the head pop off.
