250 cyl head????
welll i decided to pul my head off today after seein some moisture in my oil, and since my head gasket looked good i was gonna bring the head up to my machinist and have them go over it.... so my question is... if i leave the lower end as it is (its a 74 250), how much can i mill the head to get bout 9-9.5:1 compression, up from the stock 8.0???? figure as long as im there may as well do it... might help effeciancy and milage a little bit.... thanks in advance..
