In my humble opinion, I would try to find a let set of FI heads (E7TE) as they will flow better and most 5.0 guys replace them with aluminum.

But to answer your origional question, 351W heads from an early production run, '69 to '71. You also need to change the head bolt size (readily available in kit) and a few other minor modifications...nothing major.

I can give you complete information if desired.

Well heres the deal, the 351 heads come with bigger intake ports and valves, but not exaust ports. The only 351 heads that have these though are the 69-70 heads. All ot the other ones are just the same as 302 heads. The 351 heads are really hard to find in good shape, trust me, i found some with a small crack and they weren't fun to find. So what i would recommend is that you either find some E7TE heads (5.0L) or port your stock heads. Stock heads can offer a lot performance wise, i've read they can be good for 30hp depending on your setup. If you get the 5 liter heads dont forget to use the right pushrods becuase they are pedestal mount with roller lifters so they will be shorter than the ones you will need.

302 heads

save yourself some bucks and port out your existing heads and put early 351 int and exh valves in it. But unless you are going to be turning well over 6000 rpm a lot, its not worth the exspense of the larger valves. you will do just as well with the stock 1.78/1.48's. Also save your money on the heads as the purchase of the more "superior" breathing later heads wont gain you that much either, and they do flow better out of the box than the early 351 heads. Just redo the ones you have, unless you have a cracked one. Cubic $ = Cubic horsepower, just how fast do you want to go? And is 3-4 hp gain worth $2-3 hundred for the better heads?
