The SC2 is built from the Edelbrock Glidden SC1 casting. The original Yates SCI was sold by Ford Racing. It is a raised port C-3. The Ford Yates heads do not have side cant on the valves. The Edelbrock has some cant. Some shops are experimenting with more cant and a 2.300 intake valve. The SC2 is a version of the Edelbrock Glidden SC1.I am reading about a Ford SC2 cylinder head...what is different between the two, and who supplies the casting for the SC2?
Thanks.
Yes, it looks like the SC 2 is a big valve version of the SC 1. They are getting some impressive numbers out of them. The SC 1 is a bad head as it is, but the newer SC 2 appears to one-up it more than a little.The SC2 is built from the Edelbrock Glidden SC1 casting. The original Yates SCI was sold by Ford Racing.

Everybody loves Blow bench numbers and Google theory for sure. The ET slip will tell you if it works.Here is a good thread on the SC 1

Best programe for Edelbrock SC1
There could be something to that.... early in the event where Valve to Piston happens certainly there is something there. But that consideration doesn't take precedence over the gains of side cant. Rule of thumb may be 1 hp for every .010 ring height..... in theory???www.yellowbullet.com
Thanks for the clarification.SC2 is the new CID head. More of a play on words. Probably a much better cylinder head over all to start with. When we get into an SC1 there's a lot of welding and moving things around for the valve angles and positions we want. The CID head has much more flexibility in it. I haven't used a set yet but look forward to it.
SC1 is too damn weird. It's like 'almost' a great head. But someone decided on a 7 degree valve angle with no side cant, and ports that are way too tall...... They can make great power and i've had really good results with the Eddy SC1.... but if you're starting from scratch like Edelbrock did, you should end up with what John did at CID.........
So if whoever designed that SC1 head see's this post, what were you thinking? LOL
The Ford SC1 became the Ford Cup D3. A very good head as well. NASCAR would not approve the SC1 to compete against the Chevy SB2. NASCAR approved the D3 which has a canted intake valve, and SC1 non cant exhaust valve. It is my understanding that the SB2 has the same valve angles as the Ford D3. NASCAR mandates. Look for some D3's. You might be surprised how well they perform.Thanks for the clarification.
When I posted about the SC1's, I was referring to the Edelbrock head. I didnt think the ford version was even sold anymore.
But I understand the confusion, as I posted the thread title as "Ford SC1".
Lots of folks making big power with the eddy SC1.
I considered the D3 heads but they are difficult to find. New they are more $ than worked SC1's and GV2's, so I think I would go that direction first.The Ford SC1 became the Ford Cup D3.

I'm not advising that you choose a D3 over the Eddy SC1. Just talking some history and facts. I used to visit RYR in the old days and saw a lot of this. The Eddy SC1 from raw to finish will be expensive too.I considered the D3 heads but they are difficult to find.
