dam i wish i could edit my first post....i also have arp head studs on the motor and a set of 94/95 supercoupe headers that WILL be ported before being put on. When the headers go on the rest of the exhaust will be done also.
Probably want to go ahead and get some form of header on there. Especially with ported heads and a 10% pulley or you might be doing headgaskets sooner than you hope. They are awesome cars especially for a V6 but they are for lack of a better term fickle.
