i have a big block 402 it has a mild roller cam with roller lifters roller rocker 1.75 arms new stuts and locks i adjusted valves according to manufactures specs spin push rod until it stops turning then tighten 1/2 turn .it struggles to run thought lifters may be pumped up to tight and wont bleed down need someone elses thoughts on this issue. never had this problenm before
