I'm not saying your guy is wrong - but he builds engines for a very different purpose than a street engine and with very different parts.

Guys building race engines that they expect to last about 1000 miles or so do things differently. I have an engine builder that does nothing but circle track "claimer" engines for himself and his son. He spends pretty decent money on them but never expects to keep them around for longer than one season. He won't put steam holes in small block 400 heads because he has never seen the need...I still want them because I want my engine to last 100,000 miles...not just the summer. Just my 0.02.
