For simplicity, I am planning on switching from copper to Cometic head gaskets. My biggest question, am I going to have to machine out the o-ring groove in the blocks deck surface. Generally, what diameter wire is used?
Thanks

Al,
I have 'O' ringed tons of heads through the years & the file method is used all the time since the swich to Cometics. The main differance being, I recomend the customers remove any steel wire & install copper wire. The surfacing of the copper is fairly quick & may save the deck from damage just in the amount of time one doesn't screw w/the deck. The results are 100% good. The copper allows for spreading out in the groove a little more favorible if the grooves have been damaged & or irreglarities at the site as well.
