OLD SCHOOL WE CUT OUR TEETH ON OLDER AIR COOLED HEADS. THE REQUIREMENTS TO MAKE THIS OLDER TECHNOLOGY SOMEWHAT COMPARABLE TO THE CURRENT HIGH FLOWING DOWNDRAFT STYLE OF CYLINDER HEAD IS QUITE A BIT MORE COMPLEX AND TIME CONSUMING. WE ARE ONE OF THE FEW COMPANIES STILL AROUND WITH THE KNOWLEDGE AND EXPERTISE TO HANDLE THESE TYPES OF CYLINDER HEAD MODIFICATIONS. WE HAVE BEEN WORKING ON KZ AND GS CYLINDER HEADS FOR OVER 20 YEARS. LET US HELP YOU WITH YOUR OLD SCHOOL PROJECT. PLEASE CALL FOR MORE INFO ON YOUR PARTICULAR APPLICATION.
