I have a special construction Shovelhead with an Axtell mountain motor. The heads that came with it ...are shovel heads but with panhead exhaust spigots. They also have ports in the intake runners for nitrous. I believe there from the late 60's because they had the old style Ford large thread pitch spark plugs. Can anybody help me identify the manufacturer of these heads?

 

Almost sounds like an STD (name of the company) casting.

shovels with pan,spigot ex.you need to post a pic of these,aint no STD heads ive ever seen(and ive seen every configuration they`ve ever made)

 

There not STD heads, no fasteners at all, just 2" round spigots for use of clamps. Will take a photo and post with-in next couple of days

 

Hear's a couple of photos of my heads

 

Looks like somebody did some serious fabrication ( welding ) on the exhaust ports.

 

Now that I've seen the pics, they look like a set of HD castings that someone took great pains to fab/weld/graft Panhead exhaust spigots.
We have repaired those on Pans many times here, and actually made a blueprint/drawing of the repair spigots that we have filed with other specialty pieces/parts we've built over the years.

not sure if anyone would want to do that (???)

 

Yes, a lot of work to establish that.
If anything, a 2 or 3 hole mounting flange if one was going to that trouble.
