My Edelbrock Performer RPM works with my D00E heads (I don't remember if they are 69' or 70'). A couple of things you need to watch for.#1 is get the right intake gasket. I believe it was the Felpro #1250 is kind of universal 302/351 or use 351W intake gasket. #2 is you need to drill the heads so that a couple of the steam passages match up or your motor will overheat. http://www.mustangsandmore.com/ubb/Forum1/HTML/016572.html I apologize for the confusing post I linked to. I was just trying to get all the questions answered. #3 is that the head bolts for the 302 are smaller (7/16" instead of 1/2") so you either drill and tap the block to use the larger 351W head bolts (yuck), get shouldered bolts, or get special washers that take up the slack. Cheapest I found were the washers, Edelbrock part number 9680 for $45. HTH ------------------

William, I believe the 69' and 70' heads are fairly identical and so are 289/302 blocks. All issues apply on both years and blocks.[This message has been edited by sprcoop (edited 05-24-2006).]

Thanks you Jerry, and sorry for the intrusion Nick, just thought this would be easier than starting my own thread on the same subject.  ------------------

No worries William,I like getting the real time info from people that have either done what I am trying to do, or are in the same boat as me. I still don't know if I am going this route or not. New aluminum heads sound pretty nice too. However for the price of aftermarket heads I can get a set of rebuilt 351W heads and new coated hooker comps. Nick

65ACode, I had already purchased some stock 351W heads in anticipation of building my motor. It only took about 5 years from the date of that purchase to start. Between the cost of the heads, getting the screw in studs and having them shaved I don't want to think about how much they cost. They only had 5K on a valve job so I didn't pay for a valve job anyway. If I had not already bought them I would have gone with some World Products or other cast iron head, saved some money and got better performance.
