Cheers Max, magnet picked up most of the frags but worried about inner area and base of spring, ended up removing one of the valves.
Refitting valve, is orientation important (marked head/valve) or do these rotate during use?
Not sure what the issue is with 910 head, it was sent to machine shop a while back (see pre-chamber pics) - need to verify TDC for a clean base line and go from there.
Should be able to pull 910 tomorrow all being well, flipping hot here - has to be 35c ..I know..Arizona..is like melting the sand or something..but it's hot for us Brts
