Are e7 heads good?
They’re better than E7TE’s but they’re still iron, still have wheezing ports and chambers. E7TE’s aren’t bad-but compared to aftermarket aluminum stuff, hehe…they suck and there really isnt any other way to put it.
Are all 351 Windsor heads the same?
No there are all different ones. The ’69-’70 passenger car heads have bigger valves and flow the best. The most common casting number is DO0E. Sometime around 1977 the head design changed and requires a different intake and different length pushrods.
How much horsepower do GT40 heads add?
While we’ve seen engine dyno tests performed with GT-40P heads replacing factory E7TE castings and resulting in a boost of more than 25 hp, we have reluctantly set our horsepower gain goal at 25 ponies, as well.
Which heads are better GT40 or GT40P?
GT40 vs GT40P, which are better? Really, when you get down to it, neither head is any measurable difference better than the other. The GT40P does have a slight edge over the GT40 cylinder head because of its smaller chamber volume. The smaller combustion chamber can net a bit more compression, but only marginally.
What kind of head does a Ford 351W have?
351W Cylinder Heads. The most important issue to remember about 351W heads is which ones were just 302 heads on top of the 351W block. Beginning in the mid 1970s (1975 for truck castings and 1977 for cars), the 351W was fitted with 302 cylinder-head castings – which means port and valve sizes that aren’t any different.

What’s the difference between Boss 302 and 351C cylinder heads?
The 1969–1970 Boss 302 cylinder head is little more than a modified 351C head casting revised for use on a 302 block. The primary difference is cooling passages, because the 351C has a dryintake manifold and the Boss 302 has a wet one.
When did the Ford Boss 351 come out?
The Boss motor option was called the Boss 351. The 1971 Boss 351 could be called Ford’s greatest performance small block motor.

What kind of head does a 351 Cleveland have?
The 351C open-chamber head (2V and 4V) is a poor choice regardless of what you intend to do with your Cleveland. People associate this chamber with the smallport, 2-barrel head; however, it is also the 4-barrel head chamber for 1973–1974.
Is the Ford 351 the same as the 302 block?
A handy trick for the 351 Windsor is using parts from its cousins. The 351 is a redesigned 302 block. But the heads are interchangeable with most of the family of 90 degree small-block Fords because the bore is the same; the 351 has an extended stroke.
