I'd like to hear some details on what you've done. I do not have the skills or equipment to do the work myself, but I'd like to be able to have a good discussion with any machine shop I take the head to.
I have seen a couple of videos where they talk about getting a performance cylinder head rebuild for the F/2F engine with oversized valves. Does anyone here have experience with that? I have a spare head that I was thinking about swapping for the one that is on my rig now.
