I need a little help.I have a set of Do0e 351 Windsor heads and I need to know what size the combustion chamber will be if they are milled 30 thousandths.Right know they are 60cc.Also since they are set up with 3/8 rocker studs for an adjustable valvetrain.Can I use the stock rocker arms off of 72 302 heads. Thanks

As a rule of thumb, for every .007 milled off the heads you can expect about 1cc loss in combustion chamber volume. So .030 off of the heads will result in about a 4cc drop in combustion chamber volume. And no the stock 72 rockers will not work with 3/8" studs.
