Thanks everybody. I love this site. What I'm building is a "Steve Dulcich" 400hp 318. I don't really expect 400 hp because my porting skills wouldn't match Steve's on the 302 heads and I'll shoot for 9.5:1 CR instead of just under 10:1 as done in that old article. The stock bottom end has been rebalenced, polished rod beams, ARP rod bolts, polished crank, HV oil pump and block oiling system mods. The 302s have about 50 hrs. of grinding done with 1.94 intake and 1.6 exh stainless nailhead valves. They are actually chev valves but the stem is smaller and I could get them a little longer to give me more valve spring choice. Same cam as the article now that I know I can swap out the roller. Was going to top it off with an RPM airgap intake but came across an old LD-4B which some people seem to rave about. Either way, she's going on the dyno when done.
