Ford Guys, will 69 351 Windsor heads bolt up to a 89 302?

Buddy offered me a good deal on a set of '69 351W heads casting DOOE-C and was told that they would bolt right up to my '89 302 engine no problem and would flow better to boot, I know they would flow better, but will they bolt right up?

 

yep, you have to change bolts, the 351 w uses 1/2 bolts, 302, 7/16. ARP makes these conversion bolts,with the larger shoulder for this. Seems as though Mr Gasket also makes 'em

 

FYI Those are '70 heads. Same rules apply though Stu

 

And the 70's heads are also a good choice for 351W iron gear.

Here is a quick tech article talking about the very swap you are thinking about.

Easy to do, just follow the other guys' advice.

Although, they're not THAT much better than the E7s that came on your '89 engine.

 

From what I could find online the 69-73 D0O-E heads have larger intake ports and larger valves 1.85 intake vs. the 1.78 for the E7TE heads that I have now. Not a huge diff but a diff none the less. I also read that the stock D0O-E heads flow better than the Edelbrock performer 302 heads. Don't know if there is any truth to that one though.
