AB07 inlet valve & piston clearance question

I have spoken to Kent regarding the clearance and this is the info i was given - what i was asking was did they produce this cam with clearance on skimmed heads and here's the info i was given:

9 thou (1/4mm) TDC and 2mm valve drop

So from the info i was given what would be the last size head it would work without pockets?

I run standard Cosworth pistons and a Grp A gasket

No idea but my head has had a skim and my valves don't hit.

I would phone Grove and get them to ask Ahmed the question tbh.

Should have phoned them first actually but didn't think, will phone them tomorrow Adam

So what he basically said was if it doesn't drop and sit on the piston at TDC with at least 2mm of travel then they will touch when running at full rpm of 6500 i think that is right
