Picked up my "G" heads yesterday from Windy City Engineering (Chicago). Great people (Dale especially) to deal with, and they have the tooling/experience (30 yrs.) to accomplish the highest quality headwork.

They replaced all 16 poorly installed hard seats, cut them to a minimal/uniform depth (within a few thousands, so rocker geometry can be precise), smoothed the throats, did a 3 angle valve job and lapped them in, milled the intake surfaces level, milled the rocker stand pedestals level/equidistant to the deck, honed out the bronze guide inserts to proper clearance, ground the spring seats uniform, and tested/measured/fitted/shimmed/labeled my new springs/retainers/keepers so open/closed specs. would be exact regardless of installed height, and printed out a comprehensive invoice that detailed all final specs. They even delivered them to a much more convenient location for pick-up, which cut my travel time in half. $250 well spent!



P.S. Dale showed me the custom (?) caliper tool he uses to measure installed ht. with retainers/keepers assembled. Since I never got around to mastering the forum photo posting process, I emailed a pic to Ted. Maybe he will post it?
