[V8] cam clearence- big cams vs-heads

[J123fs at aol.com]

All the VW racers I know (including myself) do not pay for  "machining" we 
just clean the edge up with a high speed dremel or die  grinder......no fancy 
machining required! 
As the V8 heads are the same as the 16 V VW motors I can say with certainty  
that very little needs to be clearanced with larger cam lobes- just a couple  
MM's.....pretty straightforward.....though it should be done prior to doing 
the  valve work (you are going to port and change seals- valve job right?), so 
you  can hot tank and clean any fillings out.

I'll  share My info.  I have been talking to a cam regrind in regards to  
the most the 3.6L engine and early 4.2L engine can take.  The biggest  
hindrance to a huge cam in the PT/ABH is the lack of cam lobe  
clearance.   If you can get the head machined for larger lobes  your 
golden, but otherwise your in trouble.
