Yes, these are rare. I seem to recall an issue with them cracking, so I'd get them checked out before throwing them on a motor. It would be cheap insurance.

Those are kind of cool - similar in concept the the KR heads.

Wow !!!

Now I have to find a picture of the Grancore??? Heads.

 

[tubman]

Are those from an Oldsmobile?

I'm having a hard time seeing the shape of the chamber directly above the piston. It sort of looks domed, but not as domed as a stock chamber. Does anyone else see that, or does it look flat to you?

 

[JSeery]

Looks flat to me and I would assume mated to flat top pistons.

Grancor combustion chamber

Wish I knew how to make the picture bigger.

 

[tubman]

That's a "thumbnail". I "Clicked" on it and it came up to a decent size.

You done good.

Thanks, those are the heads that were onmy Bville engine. I wonder where they are now??

 

[JWL]

The Grancor are the better design for flow/power.

 

[Ol' Ron]

As you can see the heads have a sligth popup for the 3 3/4 stroke pistons. Also the piston clearance. I made a doming tool to equal the clearance. simple HC.

 

[Bored&Stroked]

I like those chambers . . . wished I owned a set of those heads! Anybody got a "spare set" that they're not going to use???

 

[saltracer]

aren't the Rocket heads kind of a mirror image? That is they have a deeper trough on the exhaust side.
