Funny you say it sucks. I am very happy that this is the problem. I have been getting so sick of it not running right that I finally got the attitude that I don't care what is wrong I just want it fixed. I had to pull the heads sometime soon anyways because I am running SI intake valves with a turbo. Plus I can fix my double roller now. I talked to the machinist and he said that usually when this happens it only takes a little honing and the guides will be good again. Plus I love to tear into my car. I thought we did good tonight, had the front head off in 1.5hrs. could have had both off but I got lazy. I guess this should be a good lesson to anyone running bronze guides.
