Ford Z-304 Heads
I recently purchased a set of Ford Z-304 heads bare. I never learn, I guess. The problem, is I ordered the recommended valves which are Manley 2.08 Intakes and 1.60 Exhaust. Well, beware, these valves do not fit the seats that are in the head. If you try and fit the seats to these recommended valves there is no seat left. I called Ford and they said that these recommended valves were the Max. size that could be fit in the head, not the ones that were really recommended. I asked then why were no other valves listed on the instruction sheet with he heads, they did't know. My machine shop which is into oval racing says I have two allternatives. Cut the valves I have, which the seats appear to be for 1.94 IN and about 1.5 Ex or see about having new valve seats installed. Not that easy in aluminum heads. I don't know what the assembled Z-304 heads have for valves but beware if you purchase them bare. I was building them with Comp beehive springs that is why I bought them bare.
