I have a 68 Camaro with absolutely stock 210HP 327, just added Hooker 2451 headers and flowmaster 17129 exhaust system. Car is four speed, 2.73 gear, all stock except for headers and exhaust system. The spark plug boots are touching the headers big time. Any suggestion for a different set-up ? Should I go with Accel shorty plugs (was told they only make one model/heat range) will that heat range work with my motor ? I'm sure I'm not the first one with headers on a stock small block. Any help would be greatly appreciated. By the way, running stock points type distributor.
