Can someone give me a concise rundown on the standard EB heads versus the very early 302 closed chamber 2V windsor heads?

Is the EB a better head? Or is it a pup?

The Cleveland head is a "canted" valve design

The windsor is a "wedge" valve design

The 2v head and the windsor head are very ordinary in std format, and either need work to make them perform. depending upon aplication another head, perhaps even an aftermarket one will do a better job.

The cleveland head will support more flow, and takes a 2.150 valve beautifully, but to properly port them, you will need a sonic tester, as they are quite thin.

Thanks, but I'm talking the 2V windsor closed chamber heads. I know the clevelands have, for some reason, assumed a sole identity to the 2V and 4v names, but those names originate from the 60's before the cleveland variety. Even the pursuit engines had 2V option. I know because I was around when it was all happening and listened to the big boys talking. It's a bit like the W suffix being added to lessor engines than the 351W...strange how generational changes occur and terms get muddled.

Anyway I digress, is the EB injection head a waste of space as a compared to the "two venturi" (twin barrel) 1970 variety?

I think those heads were the same except for h.p 289..
The e7's have better fast burn tech and harened seats..Don't read more than your cam lift when reading head flow.

Thanks for that. So the EB head is coded E7, yes?

By chance do you know the CC of the E7, so I can work out the CR?

61 cc mine was.
Cut some poly glass so it covers bore drill hole in plastic.Use a syringe and fill with light oil till no air is under plastic plate.Some grease between deck and plastic plate helps seal against leaks...Measure the amount of light oil in cc's...

OK I picked up some build date 1991 heads from a falcon. Model E7TE, which I suppose means the design is 1987 for a truck (F series).

Looking at the chamber, it's very similar to the old 54.5cc 260 head and a little bigger than the 45cc 221. So now I just have to cc this one and see if it's 64cc per the various internet sites or 61cc per your advice ebxr8240.

Thanks for the calculator site ebxr8240. I have one I wrote some time ago also that also includes ringlands, etc plus dynamic compression based on valve events, which is more relevant to me than static CR.

I have a new cam for it 218� @ 05 (280�@006)and 0.4409" net lift, 112 LSA, which shouldn't be too lopey, but give a nice burble if I run a bit rich

xpc66 · 10-01-2004, 20:59

I just cc'd the heads and it is 64cc.

ebxr8240 · 10-01-2004, 21:36

Are the pistons flat top with no valve reliefs?
I think the earlier F series where like that..Early [some] 5 Ltr where too.
If thats the the case? Be carefull with any cam as p/v is alot closser...
Does it have 3" stroke?

xpc66 · 10-02-2004, 00:07

They are going onto a 289 = 2.87". Pistons crowns have fly cuts. Standard net lift for 289 is 0.368" in 0.38"ex
