Miata Turbo Forum - Boost cars, acquire cats. - $600 1.6 Supertech spring kit, Intake & Exhaust valves

I recently purchased the items listed below from 949 but due to some machine shop errors, the head wouldn't seal. I sent the products back to Supertech for inspection and they were kind enough to replace all the intake valves, spring retainers, and 97+ valve keepers. This is spent over $800 in parts and I'm letting it go for $600. The only thing that is used is exhaust valves and the springs (which were inspected by Supertech) everything else is BRAND NEW. I can send you super detailed pics if you like.
