ive got a atc70 head,i believe it to be the same as the big valve c70 head as c90 stem seals dont fit
need stem seal and valves lapping,all there just needs putting together.willing to sell or swap for another head because i dont know where to get the stem seals from

Re: head
Usually you get both types in the full gasket sets, the tiny ones that fit inside the steel top hats and also the earlier clip on plastic ones.
If there is a groove in the valve guide it's for the clip on type.
I will buy the head off you though, pm me through the board

Re: head
It's the valve heads that are bigger (to suit the bigger ports in the head) .HarrisoN* wrote:and they seemed to small then when someone told me the C70 had bigger valves i assumed i need bigger seals?
Stems are the same diameter on all valve sizes (apart from 6v 90)
