I have a cracked head on the from side near drivers mount. Weaps coolant but not getting into oil. They are 920 318 heads.
My dads buddy has a few sets but only info I got was they have hardened seats. I am only familiar with the 675, 920, 302 as far as numbers go. I know they are not 302s as he has a set and won't part with them. What other 318 heads are there that would have hardened seats and are they closed chambered? My motor can't afford to lose any compression. Also would later 318 heads have the larger pushrod holes and air injection holes? I have a how to hotrod small blocks book but can't seem to loacate at the moment.
