Cracked Valve Guide Pillars - OK to Use?

Like Rusty said someone just did a half *** job and didn’t take the time to clean up there work. There is probably nothing wrong with your head unless the new guide is worn. If I see the top of the guide chipped like in the picture of the eBay head if the guide is still good I just machine the top of the guide down and put a positive seal on it. Sometimes depending on the cam and springs used the top of the guide has to be machined for clearance between the retainer and the top of the guide anyway so it’s no big deal
