thanks for all the input, ill list some details about the engine. i installed my tripower head a year ago by myself, i might of kinked it by struggling to get it to line up while laying the head on it. it did have a head gasket leak about a week ago, it went away though. the head was compleatly rebuilt and milled to 48cc's, valve job and all, the rockers are nos adjustable thomas mag rockers which was given a new rocker shaft, last time i had it running without the valve cover, it looked like the rockers were working great. for some reason all of the rocker pedistals had the tapered bolts, i didnt think anything much of it so i reused them i didnt resize the oil hole after it was milled last time i had the head off, i cleaned the lifters because they were very grimy from the engine sitting for who knows how long. as for the engine i bought it and my c4 from a forum member for 300 bux, the member i bought it off, bought it off some guy who said it was recently rebuilt. i had the engine in my car running for about 2 1/2 years and i think it was sitting for about a year. when i had the head off, the cylinders were smooth, there was no crosshatch, but i pulled the water pump and the block looked new, so i dont know when it was rebuilt but i will rebuild it when i get a junker to drive to work in
