i can cross refrence my head casting numbers i went to mortec
but just told me they were 75cc chambers no other specs.

I usually get out the WD40 or any other kind of dissolvant that will break loose those bad boys and save yourself some pain. Spray it - let is soak at least an hour and spray it again - repeat, then after about a day, go at it, but don't kill yourself.

If you're using the old ram horns like im used to, you will more than likely be able to break them free, but just be careful. If you find that the WD40 doesnt work, try something a little stronger.

Hope everything works out.

HEY PJ: If you live close to a Sears store they sell a socket that is designed to grip rounded and rusted bolts. I bought a whole set of wrenches and sockets from them that do just that....GOOD LUCK....DAVE

i started my engine up and let it run for awhile and then just used a long torq wrecnh for leverage and they came out easy.
