Thanks for all the input, I thought I had made up my mind but now I'm thinking about going with the N.A.P. rebuild kit with an upgraded cam and if available Flatter pistons
. That should get me descent power and still be within my price range, roughly. One more Q: today I tore down the top of the engine and when I removed the valve covers the valve train on the left side of engine was covered in sludge where as the other side looked fairly clean. Any ideas what would cause this? Took heads off and there was no sign of head gasket failure as was my first guess. I am looking forward to your guidance, thanks again.
