JSU Head?!?!?!?!?

[jetfest]

Hey so i have a jsu girdled head and im running 29 cc domes and im only getting 150-160 compression so i wanna try some 27 cc domes but cant seem to find them anywhere does JSU no longer make this head or replacement domes?!?!?!?

JSU the performance shop does not exist anymore. You might want to try contacting Steve Webster at Kommander Industries (kommanderind.com) he was the majority owner in the JSU shop and will probably be your only hope of finding any unused replacement domes for the head you have.

Another option is decking the cylinder...good luck.

the domes for kommander industries heads will interchange with the jsu heads.blowsion also has them.
