Why do you think that ? Not discounting it , but wouldn't that have caused the problem to be present from the start ? Maybe a bent pushrod or 2 ? I will check the pushrods this week , nothing is impossible , thanks for the idea , gives me more to look into . I 'm running the stock 340 rockers , nothing fancy , it's basically a stock build , a bit bigger cam , 10:5 mahle forged pistons and heads lightly ported .
