Edelbrock heads and 2291 Speed Pros

[My427stang]

Has anyone used the 2291 Speed pros with Edel heads?

Trying to help a local guy unscrew a nice little 396 FE with butchered iron heads.  Wondering if the factory reliefs have radial clearance for the CJ sized valve in the Edel head.  Small cam, and will certainly check, but if impossible, may build another pair of iron cores

Not Ed's, but ran them for a number of years under some CJ's.
No problems with my 570ish lift cam.
The black coating always made the oil look dirty even just after an oil change.

I use that combo with a 590/590 245@.050 cam and from memory there is ample exhaust valve clearance but the intake is tight radially as you suggested. I was concerned but ran it anyway. Been together 18 years. Buzzed it pretty hard sometimes, 6500 to 7000. No issues yet.

Oops.

Thanks, this one is mild, 390 with a odd Thumpr cam, low lift, lots of exhaust duration, 107 LSA with a 102 ICL.

Should sound rowdy!

Probably the most common FE combination ever assembled.
You'll be fine.

Thanks, this one has been through a few shops already and they all make the poor guy throw a lot of money at it.  In the end the heads are the worst pair of rebuilder-type iron I have ever seen.  A mix of knurls and liners, big and little seats, all sunk in the head, and valves cut beyond the margin.

Going to be an "in chassis" repair, if the Edels would have been tight, I would build an iron set.  The Edels will certainly save time
