Musky,, I listed many years ago some cast iron BSA heads and carted a few around to swap meets that came to me in large parts pile purchases. When selling them the response was rather *Ahem*
Underwhelming. I have not tracked the market recently on them but would be surprised its anywhere near what BCS is listing theirs at. I do have some cast iron preunit Triumph heads and there is a lot of variables on those, (500 & 650, external drain, internal drain, spigotted, non spiggoted, number of fins etc) and there is a nice guide to ID them on the Lowbrow site in technical. However early Triumphs have gotten a lot of interest and prices are going up...
Theres just not as much interest in the cast iron early BSAs (Sadly),, So i believe the market for parts for them is still tepid. IMHO.....
But BCS & CBS send out notices a lot about new inventory and sales & such, and both often include a little bit of used parts. I still have dealer acct with BCS, and just subscribe to CBS to see hat they are up to.
(They have a clever young lad doing interesting work, So worth watching)
So ASSUMING its the same head, (they mave serveral) Here is what was the ad copy (There is a picture too)
of the head.
" 998-67-0024 - COMES WITH VALVES; CASTING #67-25; CAST IRON. This is a really good condition complete head for the rare long stroke A7 models at a super price. We have lots of parts for these early A7s, including genuine NOS BSA head gaskets.
One fin damaged, see photos.
Dealer Price $300.00 USD"

So, *Ahem* a little steep me thinks, but perhaps thats fair?? But they are a big & successful company, And their staff have been good to me, Mark the Owner is a good guy based on my dealings with him, and perhaps they have acquired a trove of treasured used parts so worth a shot asking if theres anything one needs?
Their hard copy catalog is a nice bit, and my copies have a treasure trove of parts interchange including a really handy listing of pistons, specs and part numbers, Same with valves, cables and other specs. So, not sure their current printing, but a worthwhile reference.
(The old Dommi racer/Accessory mart old catalogs were ALSO packed with great tech materials. I was a dealer for the commercial side -Dommi, And the retail side was Accy mart. I also bought some of their wall charts as well. The Triumph gear box chart is a treasure and IDs all the tooth forms and shaved, non shaved, stepped, non stepped, ratios and every part number. Their sales flyers had a poster on one side, and stupendous deals on the other. I am sorry they are gone, a great resource, But their old catalogs sit right on the shelf above my computer and I use them often. Every cross reference you can imagine.)
