ciavola Posted June 3, 2009 Share Posted June 3, 2009 I am reassembling my motor, all stock. I had the Head resurfaced. cam regrind. I thought I had read where you have to use a shim with the head gasket if you have had the head resurfaced? Anyone have any info? Quote Link to comment Share on other sites More sharing options...
MikeBZ Posted June 3, 2009 Share Posted June 3, 2009 Depending on if the head was shaved, and how much, you might need spacers under the cam towers. Quote Link to comment Share on other sites More sharing options...
2eighTZ4me Posted June 4, 2009 Share Posted June 4, 2009 If your head has had (aggregate) more than .015" taken off of it, then yes, you need shims under the cam towers. MSA sells them in .015" increments (how convenient!). You don't need to do anything to the head gasket side. Some folks shave the head down a lot (.080") to boost compression ratio, and build up the cam towers with multiple shims. Keeps the timing chain taut and keeps cam timing far more stable due to less chain slop. Quote Link to comment Share on other sites More sharing options...
