3) And how do I know when they're all the way "in"? The top of the guide should be flush with the block.
Reviving an old thread - this is the exact problem I've been trying to find (lord, google is your friend *and* enemy!)


SO from the head side, drive them in, small ID first, until the top (larger OD) end is flush with the bottom of the valve cavity?
