If i recall correctly some triumphs have cast iron guides in alloy heads. The were great to get out because you could snap the exposed part off, where the circlip groove was, and drive them through so you didn't risk scratching up the guide hole in the head by getting them out the way they went in.
I Didn't know that Chris, my first bikes were a BSA and an AJS all of which had Bronze guides alloy heads but all of the vintage stuff has cast iron Guides.
@@bobrodgersonsmostlymotorcy9265 that would be the logical mixture. Triumphs with alloy heads were a constant source of aggravation, guides coming loose and cracking being two of them. It would have been better from mechanics point of view if they had stuck with cast iron, or perhaps not as it was more work for the working man to do.😉

always thought that using a bolt and nut is the better method to remove & replace valve guides.....much better that a hammer
