Guys,
For those who were in on the thread about problems that can arise from aftermarket heads, I thought I would let you know what I found on my new 230cc Dart Pro 1's. I only had time for one head, but I found everything so far to be above my expectations. The the valves are all properly seated on the flawless, 3 angle valve job. It may be common practice, but the heads were actually blended to the seat and the first 3/4 inch of the bowl was cleaned up where it looks like casting flaws may have been. The valves were nice, swirl polished, undercut stem stainless with no nicks or problems at all. The valves were also all installed with a red assembly lube of some sort and the guides all had the slight play machine shop tom described.
Perhaps it is just that I am just used to looking at machine work on oem heads, but I am more impressed now than before I disassembled the head. I can't tell you how nice everything looks. Definately the best money I have spent in a long time.
Later,
Chris
