Tom's has had a long tradition of offering our local customers engine performance kits, that include simple port modifications to aftermarket big bore kits. Currently we offer installation of several company big bore kits, and porting as well as aftermarket heads and domes. We also offer modified stock heads with replaceble domes that fit inside existing stock heads. These heads have been machined to accept the new dome design. This will give you the stock appearance head, but with the increased performance.

 Prices range from $590.00 for a ported set of cylinders that also includes renikasiling your used cylinders, to $2,200.00 for big bore kits. Prices do not include any labor or clutch kits and is in addition to these prices. Head prices range from $290.00 up to $495.00 for anodized heads
