View Full Version : Head identity
Are there codes on the heads(willy and valver) to identify as to what it is? If so what are they?
Cheers
measure the inlet valves, 30.7mm is the valver one's think williams ones are 31.2??? im sure someone will correct me
Dave
1.8 are 30mm inlet
2.0 are 32mm inlet
both are 28mm exhaust.
im sure the inlets are 30.7... not that .7mm would make a difference ill find one, got 3 valver cylinder heads here lol
Dave
Just found a valve, measured across the face of the valve its 30.7 mm
Guessing the seat outer diameter is 30mm
Thats a 1.8 16v head btw
Been informed that valvers are 30mm and willy is 32mm...
