Below is an example of the head work I do. Thses heads have been shaved .075 ports have been massaged tremendoulsy not so much making bigger but making it flow!!!! Exhaust port and combustion chamber has been polished, intake port is not polished but smooth flow wise and swirled to enhance fuel and air mix and atomization. I like the stock valves they have been lightened and polished 3 angle valve job. I did some light machine work on the exhaust side where the springs sit and used E.C. dual springs and billet retainers.
For the budget wallet racer, I will re-jet your walbro carb with an adjustable main jet and then rejet the low side to better the fuel curve needed for race motors. 45.00 plus return shipping. There are no other mods to the carb no boring or polishing simply rejetting for racing. A EC filter adapter and filter can be added for 30.00. SO for less than 100.00 you can have a good solid no fuss dependable race carb. I will rejet twin carbs for the same fee. Filters and adapters are availble depending on carb.
