Also, You could take the head to a machine shop and have the valve seats recut. Then have them grind the valve stems to a more normal clearance of about 2MM.

Nevilles cams always drop right in, everything is very close, he knows if youre gonna shave head, do valve job or anything he wants to know when he makes his cams, we all know this.
Still wandering about street/fa cam upgrade? Checking valve clearances on the rocket is tricky, your numbers are very out of spec, makes me think something is up with your checking method or base circle on cam is off by atleast that 1mm. 4mm shims seems excessive.
You might be right, have never been close to 0.93 gap with feeler gauges before. Will know in a few days when a shipment of 2.45-3.15 shims and 1.1 mm lash caps arrives. First thing I'll do is to fit a 3.15 shim to the intake valve having max clearance and see if I still end up with the same number.
