I'm planning my build of a D5 head and I'm going over the final details before I start ordering parts and sending stuff to the machinist. I was planning to go with the larger 1.50/1.75 valves but I was wondering what issues would arise if I went with the slightly larger ones offered at ClassicInlines?
The way I see it, the machinist is already going to need to enlarge the holes, the only difference is what size "drill bit" he's going to use. So where am I going wrong in my thinking? Are the results worth it?
NOTE: Optional valves sizes (over 1.50/1.75) require custom machine work to maintain proper clearances. Verify prior to ordering.
