351 Heads?!

[zZsKyZz]

Would 351 heads fit our engine? Would they be better than gt40's?

Does anyone use them in their combo?

Yes, 351 heads would fit but you'd have to get those reducers since 351 heads are made for a 1/2 inch bolt.

As to whether they are better than GT-40 heads...I doubt it stock, but if you get them ported well, they probably are. But I don't know for sure so take that with a grain of salt.

FWIW - IIRC, ARP also makes a bolt (kit) that has a 1/2" shank and 7/16" threads so a reducer is not required.

The best 351 heads are the 69 & 70 heads. They are probly not as good as GT40 heads, but can be ported to be much better, more material to be ported. In the mid 70's, the 351 & 302 heads were the same.

late model 315 heads are also the same as 302 heads
