Re: valve guides in 59ab
I recently decided to put a really fine knurl on the OD of the guides - tested it with an old one first. When they are pulled up into the block, the knurling is almost completely flattened down and the guide does get quite a bit more 'snug' in the bore. As Pete noted, this isn't the most scientific/best way to do things (especially for a competition engine where heat is more of an issue - I like his 'copper plating' method) - but seems to work fine so far.
Here is a link to a couple videos that I made: Problem: https://www.youtube.com/watch?v=qZBXFMqHs-c Little Knurling Solution: https://www.youtube.com/watch?v=UqYqBIy1BAI Note: I also use an o-ring on the intakes and I always use the correct exhaust guides on the exhaust side. The exhaust guides should NOT have the o-ring groove cut into them. I see a lot of companies selling 16 intake guides in their sets - I won't go this route. I want as much surface area as possible on the exhaust guide ODs (like Henry did) to take heat out of the exhaust valve and transfer it to the block. |
