This ad is for work to be performed on your heads. We don't do a textured finish... Why???  Because to us textured is not finished work... Our work is smooth and meticulously hand finished! If you buy a set of used heads off Pricetronic or anywhere else, it is recommended that you purchase one of my services before bolting them on your bike. This is a cheap way to insure the heads you just bought are in mechanically sound condition and are ready to bolt on, while adding some Horse Power as well! Ported and Polished heads will be a compliment to the other performance parts that are installed on your bike. Stage 2 Heads perform great between 2000-6200 rpms! Stage 2 head service is great for building 95 -110ci motors. Turn your Stock Heads into Performance Heads! Stage 2 Heads will support over 130 Horse Power and Torque! Stage 2 service will to take your build to the next level of High Performance! Gains can be expected in the range of  10 - 20 Horse Power and Torque over stock heads with a good cam and a tune! Polishing of combustion chamber : ( most porters don't polish the chamber or ports because it is costly and time consuming process.) 1. Helps Prevent Carbon Build Up - Which lead to hot spots and pre-ignition/detonation 2. Reflects Heat - Resulting in cooler head temps and a more dense air charge creating more Horse Power and Torque! 3. Better Fuel Economy - Resulting from the reflection of heat, aiding in a more complete burn in the combustion process. Modification includes: De-carbonize, Disassemble, and Inspect Polishing of Combustion Chamber Combustion Chambers Size Kept Stock at 85-86cc Full porting of both intake and exhaust runner. Polishing of both runners to ideal surface. 80 grit intake for increased velocity and better air/fuel atomization Fully polished exhaust keeps velocity high and carbon build up down. Retaining of factory guides and springs (unless upgraded)     Competition valve job     All gasket surfaces are cleaned and lightly sanded to assure proper seating of gaskets.      Machining of valve seats for oversized valves.    Stainless Steel High Flow Valves    1.900"int/1.610"exh.         Things you might want to add or send:     New Valves - included with purchase     New Springs - can be provided by me (for additional cost) or you can send them with your heads Machine and Install manual compression releases - $150.00 buttons included Stage 2 heads will create greater Volumetric Efficiency (cylinder fill) and Velocity (faster air speed), in effect producing more torque , and at the end of the equation this means more horse power! Resulting in faster acceleration and a more efficient running engine.

Hands down these Stage 2 heads will out perform most of the over priced heads on the market including the Dealership cnc serviced heads at($900). The Stage 2 heads velocity will be substantially higher than stock, thus allowing more cylinder fill which equates to more torque and horsepower. Stage 2 heads have been known to produce over 135 horsepower and torque with the right cam and tune. That being said, bid with confidence and get more bang for your buck!   Outside the lower 48 contact me for shipping prices before you bid or use the buy it now option .
