I have found a complete running 12 valve. My question is would I be better off to buy this and rob what I need to do a conversion and sell what I can of the rest of it or just buy the parts I need? So far the whole running engine is the cheapest route but I'm just guessin that all the stuff from it would work. I have done some research but still kinda foggy. I can get the 12 valve for 1300.
