hi all i am hoping someone can help me .i am at the final stages of assembling my 292 and have two questions that i hope someone can answer first is thermostat temp. i was supplied with a 160 degree and i think this is too cool and think i will use a 180 ??? any thoughts??.second is intake manifold gaskets. i have a felpro kit and also McCORD and others and they have 2 gaskets of which i am not familiar. one has a restricted middle port  , where the hot air goes through and the other is open. i was thinking it gets back to auto and manual choke for heating the manifold. i will be using the 4 bolt 2 barrel holley with a manual choke. hope someone can put me in the right direction. cheers will try to put a photo.
