new engine build or buy long block ?

I like the way she purred. What are you doing to break it in? You went roller cam right? If so, you don't need to worry about adding zinc, but you should still work it through all rpms and multiple oil changes.

Yes , valve train comp cams says to bring it all up to operating temp and then back down to ambient temp . The roller cam only needs oil and the I'm running 5w30 conventional oil from oriellys , it's good clean oil and I'll change it after the first 5 hours to see what's going on through a coffee filter . I'm gonna break it in under power loads , my opinion the piston rings are worn in under loaded conditions and the compression is what sends the rings outward to seal things up for a reliable engine . Since I have full roller rockers I may have to adjust lash but this is my first roller build and I've dialed everything in from springs to valves , compression ratio , porting . So she should run in pretty well .
