Does anyone sell fresh casted cylinder heads for us? Cast iron is what im lookin for. I do not have the loot for the gn1s. But, I have been known to port a mean head tho! So it is not really that important to get the gn1s. I reallyt don't want to go to the junkyard but i wiull if i have to. The reason for all this is becayse I changed my oil and found a piece of hg material on the magnetic drain plug. Must be starting to blow it into the intake again!
Also my overflow bottle seems to raise a little and start to wave a little when i mess w/ the throttle. Temps r a little warmer than usual too.
