I don't want to get a new crank. The one I have is forged. I really don't need it but I'm not going to get crap for it if I go to selling it. I see the biggest problem I'm having is the heads 98cc isn't that much. The smallest pistons I have found are for 100cc and are close to 10.0 to 1 ratio. I'm going to be driving this car alot and would like to run it on normal gas with no porblems. Does anyone recommend a stock cast head that I could use and locate easy. I've heard about the 781 and 049 but around here you are pressed to see any of they on any thing but a race car or a shelf with a huge price tag on it. I've also was told about the #14096188 heads how are they and about what price should a used set cost.
