Here's Dart's description on your heads....

"Maximum performance, Full Competition, unlimited Oval and Super Classes over 7000 rpm, 400+ ci"

Why in heaven's name did you choose these heads for a daily driver? They'll make power from 4,500 to 8,500 in a 400+ cubic inch motor. You won't believe how horrible they'll be in a daily driver 350 street motor. No power under 4,500 r's. Sell 'em on ebay and start over with some 180 cc heads would be my best advice.
