I have a head bolt rethread kit made by Huhn Solutions that was used once. This kit can be used as is to do Northstar v8's and baby northstars, the Olds 3.5 v6 and the Aurora 4.0 V8. It can also be used to repair Toyota 2.4L 2AZ-FE and 2.0L 1AZ-FE motors with a spacer sold by Huhn. This kit was over $500. You can buy the inserts from Huhn for your specific vehicle. The insert were very easy to install and worked like a charm. I need to get $150 for it. Thanks.
