So I've been reading around about the spi and about the problems, so here's my question. I have a great running engine right now and I would rather not swap engines, I want to just try to make mine so it doesn't have the valve seat problem. I heard there is a head out there that I can buy that fixes this problem? So if I did this would I just have to replace the head or what? As much information about this as I can get would be greatly appreciated!
