OK I just had a lot of machine work done at a highly recomended machine shop.........he put my cam plug in block backwards,now I am wondering if he did anything else wrong,I have two questions about my heads. I had them surfaced,competion valve job,hardend seats,new seals,new valve springs(I'm going to run a comp extreme energy 262/270 duration,.513/.520 lift cam, he set spring pressure at around 100 lb closed 300 lb 0pen) first? is: are the valve seals susposed to move up and down easy on valve stems?(they didn't look like they where down all the way on the head, so I used a plastic glass tool to gently push them down,what keeps them in the correct spot?) the second ? is : are the inner damper springs suspose to be touching the outer valve springs? (they wind differt directions,don't think they would ever get in bind,but not sure if they should be touching????
