    So where does this Forum stand regarding loading rebuilt heads onto an old (and very wore) block? My son believes you will get blow-by that you didn’t have before, because your new heads are tight and your compression will reach pressures it hasn’t seen for quite some time. I don’t have a desire (nor money) to rebuild the engine right now so I want to go with rebuilt heads and try and get a few miles out of this 1986 Ford F-150 with a 302.
