Crossflow valve piston Clearance?
Evening all, looking for some advise on the normal crossflow valve to piston clearance at TDC.
I have pockets machined into the pistons currently 0.50mm clearance between valve and piston at TDC. Does anyone know a round about figure I know this
changes depending on cam etc...
Burton are saying 1.5mm minimum as are a lot of places however looking on piper and Kent technical sections they are saying around 0.5mm?
Help please,

As a xflow user, i would go with the 1.5mm as per Burtons, .5mm seems a very small gap ?

On the Pinto clearance should be .75 to .9mm depending on peak revs due to rod stretch
It will be the same for the Crossflow
