86 vette...proper way to adjust the valves....
86 vette....I have that high plenum. trying to get car back on road. put new heads on engine when I start car there is a popping sound I think I have the valves too tight or loose. also right behind the throttle position sensor there is a nipple that sticks out Is it air or water. the vaccums that run under the plenum, what would be there correct routing. a diagram or pic of that info would help 100%. thanks
