Hi guys, doing my first engine rebuild with a 1996 mustang gt motor it is the 2v romeo bock. I'm using a a book I got from O'rileys auto parts to do the rebuild but would like some advice from the experts. Because of my age I have a limited budget (about 500$) to rebuild it. I'm planing on selling the NPI heads and put the money towards some used PI heads. Any advice would be appreciated.
