Quote: Well..My gut was saying that I should replace all of them too. I can pick them all up at Summit for about $225. It will be worth the peace of mind. Is there a reason I should not replace the valves myself? I have done a couple many years ago. but never all of them and never on aluminum heads...Wouldn't think it would be that hard. Compress spring, remove locks and slide valve out...Reverse to install. Am I off base here?
You need to check stem to guide clearance , do you have the tools to do that ?
