head identification

[John Cody Forbes]

NF heads are unique among 10v heads in that the intake valves are 2mm larger 
@ 40mm. That's the easiest thing to find. Part numbers and casting numbers 
are the same between MC and NG heads (I have both literally in front of me 
as I type).

If this one on the marketplace doesn't work out I have one I might consider 
selling. I use them on my 'fast' 5ktq and have one extra.
