TAKE THEM BACK. Hopefully he'll see he doesn't know what hes doing and give you a refund for the work and new cylinders. Of course that probably wont happen, and you got screwed. Next time use a reputable builder - it goes a long way.
Why such small domes? I wouldn't recommend less than 20s at your elevation and mods. No need for race fuel. And your list is kinda off, the 4 mil has to be done with the porting. If you port stock stroke it wont work for a 4 mil down the road without being re-ported (if it infact can be port matched).
Never had them personally, but many on the HQ have in the past. They are a great top end pipe. But goodluck finding a set. Better off getting CPIs or Shearers if you want top end and not much bottom.
You need a press. Have a reputable builder/shop replace it. You might as well just get a new hot rods crank while your at it (on second thought :biggrin: ).
Direct Drive is a simple, easy change clutch cover style lock up. Not to mention is has the window for the lookers :biggrin: . John at Sandtoyz Unlimited will hook you up with a killer price.
