Looking for opinions. I am running Indy 440-1 heads with external oil lines to heads. Just freshened motor. Installed aluminum main caps and girdle. New roller lifters. New pushrods. New Harland sharp 1.6 ratio rocker arms. New oil pump. It has lower oil pressure than it had before rebuild. I had the top end restricted at .070 using Indy rocker arms. Now restricted to .045. Oil pressure still low. Top end is flooded with oil. Anyone out there have experience with this issue and how small is to small for restriction. Never had any issues in the past 1000 runs with this prior to new setup
