I've got a 194 chevy head that we've put in lumps, milled .040, 1.94 intakes, 1.6 exhaust, pinned studs, bowl work, unshrouding valves, etc and I need help selecting valve springs. The cam is a 28O duration hydraulic, 560 lift, 231 duration at .050" and this is in a 292 chevy 6 cylinder. Originally I was going to go with "Z28" springs (according to Leo's book) but discovered that those are good to about 510 lift or so. Rockers will be comp's long slot 1.75's (stock ratio) so nothing special there but spring selection I'm needing help with.
