I do have good news the oval intake ports line up perfectly fine and a valve job was done to them. had an old set of intake gaskets laying around they fit .. there is some meat for porting so that worry is out of the way. also I just got a set of the kb icon pistons with a 41cc dome on it so I guess little chamber heads are out of the question now haha.. I checked for valve clearance and we had close to 1/8 inch of clearance... is this a good thing or a bad thing?
