Well.............. We do them in house with known good parts(valves, springs, spring Cups, seals, retainers/locks, GUIDES), Good 5 angle seat/2 angle valve Valve job and hand blend, plus we fix 2 critical areas that need attention that No other shop is doing. I know this because I have had the other shops heads in here for a "check over". Not being done.
Without porting, I sell them for $1495. Porting options are stage 1($250), stage 2($450), and CNC($1000).
Complain all you want about price, but we take care of the known issues and when they leave my shop with my name on them, they are good to go!
