428 running rough |

I'm having a little trouble getting my 428 CJ to run smoothly. It was rebuilt with a mild PAW hyd cam, stock heads and adj factory rockers. It ran very good, but had to be taken back out for other unrelated reasons. While it was out I decided to have hardened seats installed and I picked up a PI intake. Now after reinstalling it, it runs a little "lopey" compared to before. I took a straight edge to the valve tips and noticed that the shop that did the valve work didn't get the depth even on the valves, some are almost 1/8" off. I adjusted the rockers at 0 lash plus 1/2 turn. Will the adjustables be able to take up the difference, or will I need different length pushrods to make the correct geometry? Thanks for any advice. |
