I have two of these left, and they are almost certainly the last two I will ever make.
I am selling them for $145 each, but I am looking to trade them for some or all of the following:
F4, R2, R2+, R5 cam (in good condition, regrind is not desired but I will consider)
Crane springs
+2mm Intake valves for G head (not literally +2mm..you know what I mean..the biggest ones that fit)
+2mm Intake valve seats for G head
PM me the trade you are thinking of!
