It does sound like you have a combo that would favor this head?
What combo are you building?

So what combo would this head be legal for? It looks like a decent head for modified stock SS/AS ?
I remember it was a novel idea, to watch STK SS cars, with original power plants, (OEM parts mostly) and see how fast someone could make them go. That was entertaining, and sometimes still is. I was never in favor of aftermarket castings.

What would the unported price come in at?

A few years ago, several guys wanted a Brodix headed spec class.
I belong to the Modified Fb page, and admire that old class, but really you can still build that type of car with better parts today.
Why not admit you really want to run modified?

Hi Don,

The cylinder is not for my use. I was asked by several engine builders and cylinder head shops to help them find an aluminum casting as a substitute for the "not available" NHRA SBC-approved cylinder head.
I am actually a Ford guy and my new car is a Ford!

Anyone expecting new NHRA-approved cylinder heads from Edelbrock, is just wasting their time. I submitted many brands of 23-degree SBC heads to NHRA and they were rejected for one reason or another, with no sound basis for the rejection, including a cylinder head from TFS with an as-cast runner of 175cc. Let's be clear, this is for Super Stock class racing, not Stock class. You are allowed welding, epoxy, CNC machining and more.

The cylinder head I proposed to NHRA is a 23-degree cylinder head, available both for center and perimeter bolt valve covers. Profiler does not show the cylinder head in their catalog, however, it is available over the phone. The intake and exhaust ports are small, allowing them to be ported for many of the SBC engine variations with small ports and small valves. The chamber is already finished. This casting would be cost-effective for the racers since you can develop a port that will not require welding and/or epoxy. The casting is made in the USA from aerospace-grade aluminum and is thick everywhere; no more worries of leaking spring pads or cracks. Besides, in the event of a failure, it can be repaired.

The Profiler castings are currently available also. Lots of them as a matter of fact.

I have attached pictures of the cylinder head that was submitted and the brochure with the specifications of the cylinder head.
