When I built mine,

I have AngloBike half race cams ( same as N. Hyde?) which use standard timing.
plus heavy duty valve springs, dural valve collars.

different exhaust as well.

Martin, that is a fantastic job of cleanup on the head. Sorry, I'm not a "non-spec-savvy" guy, so I can't help on the cams.

@DAVE M where dis you get that heavy duty valve springs and dural valve collars?

@GrandPaulZ it was done by local machinist 3 valve angle and full porting polished...

just bought a new wessel valve and guides, but i look around people tend to buy the black diamond valve, i also don't know where to get it...

i do some browsing for cams, 750 intake cams and 650 exhaust cams is a good combination of cams... and still using standard timing.

but found nothing on jomo15 or sifton 390 no review on street use....

"The T-75 is stock 750, pretty hot. The T65 is a BSA Spitfire grind. Your best bet is T75 T3 (Triumph triple). Sifton 390’s not so good for your purposes"

just got back from my cams maker, this is his reply please gives some comment for it.

either T-75 intake T-3 Exhaust or T-75 intake T-65 Exhaust
