"Semi Hemi" is one of the nicknames applied to the Big Block Chevy. Went from Mark V Mystery Motor to Porcupine to Semi Hemi. Later on went to define all canted valve wedge engines like the 351C.
The \6 cross section looks/shows to have a "wedge" combustion chamber:

Yes. The slant is a wedge engine, but we weren't talking about the slant. We were talking about the Hemi Six. Completely different animal.

Stupid question maybe but was there ever an aftermarket performance head manufactured for the slant six and is it still avail/how would I go about locating one?
Correct. As far as I know, there is no aftermarket head available for the slant six, Although, at one time or another, some have been made, in very limited quantities, for a very specific purpose.Ok so Ill take all that as a nuthin avail. Thanks Charlie, interesting but not realistic for what Im after
Charlie, have you talked to Frank lately? Has anybody for that matter? I sure do miss him around here.

Ok Ill take one of these, sounds like its what Im afterOnce apon a time there were heads done by Yella Terra....they were OEM heads that had been crack tested, checked, modified, ported and flowed on a bench.
They haven't done them since the mid 80's, me thinks.
If you want a reworked stock factory casting, you can have Mike Jefferies do one for you. He will do anywhere from mild to wild. You need to tell him what the head will be used for.Ok Ill take one of these, sounds like its what Im after
Where do I sign up
I talked to Frank about the end of October, he is happy and enjoying family, I called him just in case I needed to sell my big valve shaved head he built for me and said yes he would by it, but I made everything happen with out selling it.Charlie, have you talked to Frank lately? Has anybody for that matter? I sure do miss him around here.
I havn't in a while. I guess it is time to give him a shout.Charlie, have you talked to Frank lately? Has anybody for that matter? I sure do miss him around here.
I agree Charrlie :coffee2: I may give him a call about 1 pm eastern time, I bet he will be happy to hear from you and I on the same day :coffee2:I havn't in a while. I guess it is time to give him a shout.

I could talk to Radar from R&J Performance . He carves Hemi heads out of billet quite often. They scratch built a billet head for a John Deere pulling tractor. lol It would cost thousands and then the intake to make it work. Headers not quite so hard to fab.
I agree with Bill. The most cost effective way to make big HP numbers with a slant is a turbo. To get the same numbers normally aspired, would make the engine unstreetable. I did a real simple turbo slant back in the late '70's by putting a Corvair turbo on a 170 65 Valiant. I could drive it to the track, open the exhaust, put on the slicks, and go 13.4's at 104 mph. About 10 lbs boost.The hardest part was the "tuning". Back then there was very little turbo info available to the "hot rodder", no boost timing master, no air fuel ratio gauges. All I had was a EGT from a airplane. My water/alcohol injection, was a windshield washer setup, with the nozzles spraying down the carb. Triggered by a 5 lb pressure switch.
