i would go with highlifter's kit. i can sell you one for a good price to.
they use good parts but you need a good machine shop to resleeve the cyl and port the head. i think porting and polishing is great and reduces carbon and gives a little extra HP , just find a motorcycle machine shop that does it full time and in-house. not a auto shop. maybe a cam too.??
