hi guys recently i posted the combo in the truck that i just bought. It is a 400 sbc that i bought not too long ago. It has three lobes wiped out on the 268xe that was in it. When i pulled it apart, i found that it had a cloyes hex-a-just timing chain set, with a needle bearing cam button, and the torrington bearing behind it. I thought these were only needed for rollers. Will it hurt anything to use it again, or should i use a regular chain? I have a regular cloyes true roller new in the box, but would like to use the one in it if it won't harm anything, it looks like it mates to the aluminum cover nice, but i'm worried that this might put unneeded stress on the cam. thanks again guys.
