Heads vs. Manifold
351W block 302 Heads I have had the same trouble before on a 351 with 302 heads, just want to check with the other members concerning water leeks.the heads are of C80E (1968) when I place the manifold gasket on them I have an area that dose not get coverd and must be pluged with silecone.Is it the year of the heads or am I using the wrong gaskets?

well I am useing the early 302 with 58cc chambers,the gasket covers all of the intake just fine and most of the head.But at the front (right head) and the exact place on the left head wich of course is at the back,the gasket is just larger than the matting service. I will look up the ford part #s thanks.JNT

If you're trying to use 302 heads on an early 351W, you must also swap intakes to a later (77-up) 351W The early Windsor intakes have 4 extra bolt holes in the coolant ports (1 per port) that will be open holes if you use a non early Windsor head under it.

Well this is engine #2 that I have done in my shop (351W) with 302 heads and felpro gaskets,that have given me trouble at the afore mentioned spots.If you do not put sealer in the corner of the gaskets you have a water leak. I do not under stand why its just me!

here is a 351W head i ported..only pic I could find......
I can see where the intake might leak if the bolt hole was not pluged or the early intake was not used like baddad457 said.....

Hemieater, I do have digitale, but other than posting pics on my gallery, I have not gotten any in postings. The block was recieved with out heads, and as you say they are very close to the same,the recon heads are of a 302 also his work (a frend needing help) in lew of money that seams to be the way I get paid but I am retired so thats cool.
