Hi guys

Can anyone point me to a supplier of these? They are not easy to find. I have 4 of them I have to replace (rest can be fitted with bronze inserts). Even if I have to fit full bronze guides to the 4 that need replacing would be probably OK and the rest can just have inserts.

Trw makes them, plenty of info on the net, should be available at Napa or any engine machine shop.

Thanks mate.

NAPA, Summit, Jegs don't list them. Nor do Sealed Power that I can find. I cannot find a TRW catalogue online.

I thought they'd be easy to find too, but have not yet found them listed anywhere. They all sell the .502" OD examples but these are 0.555" OD. They are the same 11/32" valve stem and same length as the cast iron head type but larger OD. I did find some old blue flame 6 guides that could be machined down to fit which is what might be required. Also found Sealed Power VG-1375 which is what Sealed Power list for 1985-1990 alloy heads, but these are 3/8 stem and 0.6205" OD, which in a pinch I could get the heads modified to take and the ID isn't so much of an issue as I plan to fit thin bronze guides.

Yes, the guides could be machined to fit bronze guides, then they are final fitted to your size valve, then the seats would need to be redone. Not a cheap job!

All of them have to have bronze guide inserts fitted, but 4 of the actual guides are gone and need replacing. These are the cast iron inserts pressed into the alloy. I still have not located a replacement, as above only guides for other engines that would need machining to fit. I wonder what used to happen when these were far younger engines and guides were damaged?

Sounds like some type of replacement head/s are in order.

Not over here. It costs way to much to freight heads to Australia! Small parts are cheap, but larger stuff costs a fortune.

Got it, didn't know that's where you are.
