CNC Porting of low mile LS2 (243) heads
CNC Porting of low mile LS2 (243) heads What a delima! I have a GTO LS2 engine with only 600 miles on it going into a '68 Camaro Convertible. 
With it sitting on an engine stand I figure its a great time to tweak it a little. I've also come across a set of new LS6 valves (hollow stems and sodium fill on the intakes). I thought I would have them CNC ported and set-up with the LS6 valves. The problem is the cost differential between having the work done or heading down the L92 path.
I know that GMPP heads are ported by Lingenfelter but they are expensive, especailly relative to the L92's and if I bought the L92's I should be able to offset the cost ($500-$600) for mine as they are practically new. I don't necessarily want the L92's its just that there's nothing wrong with mine and I just want to clean them up for more flow.
It's not my intent to incite a riot here but I'd like recommendations/quotes for which shops/sponsers offer, say, Stage 1 CNC porting and installing the LS6 valves. PM me if you don't want to go public.
Thx!
