Budget racing the old nuts & bolts

Did the first oil change today. And then a cranking pressure check. I was very curious - first time valve lapping. 150 - 154 except #8 160? That #8 plug was moist as well. I don't think the rear main seal is happy. A few drops of thick clean oil on the bellhousing bottom. I'm not sweating that.
That poor 318 gets beat on at every opportunity on the 16 mile drive to the track, at the track, and all the way home. An sits there and returning to it's choppy idle as if to say- "that's all you got?!" The 904 - absolutely FLAWLESS!!
