Roger guides can be changed But they tend to get stuck in place over time and driving them out can lead to mushrooming. I core them out and leave a step to drive them out. You can tap the guide and install a bolt and try tapping it out. To install guides I coat them with a synthetic anti seize and drive them in with a stepped driver I got from my local snap on dealer.That was the easy part the guide then needs to be sized as it can distort or the Id can shrink when installed. Two methods for sizing guides are honing and reaming and because most guides are silicone bronze a carbide ream is needed. I spent the big money and bought a Sunnen hone to size the guides So this is not a common backyard job and you might consider having a shop take care of this for you or better yet spring for the new heads my price is $450 each prepped and readty to install Bob Donalds boston Engine ----- Original Message ----- From: "roger sisler" <rogersisler2000@YAHOO.COM> To: <vanagon@GERRY.VANAGON.COM> Sent: Wednesday, November 08, 2006 3:56 PM Subject: Cylinder head repair question
