I have a Firebird with the Pontiac 400 engine. I am just putting the engine back together after a crank regrind. Haynes tells me just to tighten the rocker arm pivots nuts to 20 lb-ft which is what I did last time I had this engine apart and I am wondering if this is what caused the 2 bent push rods. I have read elsewhere that I should tighten the rocker arm nuts so that there is no play in the push rods and then tighten them another half turn. I have tried this but they are nowhere near 20 lb-ft. (except for the 2 where the nut has "bottomed out" at about a quarter of a turn). I am worried that they are going to rattle loose. What is the correct way to set them. Thanks for any information.
