Bronze valve guide liner install J heads question for machine shop guys...

Valve guides really need a machine to install to do them right. You bore the guide hole, install the guide, machine or ream to the correct size and check to make sure the valve is seated properly. After guides you should have the valves and seats ground to make sure it is all correct.

I have read about that if the guide isnt reamed straight the head is toast etc. I beleive there is no way to do it freehand hnece that Lisle 59000 tool that noone can find I beleive that trues it up for reaming. In reality I beleive the cost of the tools wouldnt be worth it unless I was to start doing heads as in quite a few sets over time etc. I have a 340 bottom end tahts just about together and a set of 1.88 heads ready to go but really want my set of 2.02's redone. Time to ante up I suppose.
