I was searching for what I should gap my plugs at and realized that there are quite a few people running TR6. Am I gonna be able to use these plugs with my heads? I was just going to exchange them but wouldnt you know it I dont have my receipt.

 

You will probably find them to be a little too hot particularly if you took the opportunity to raise compression. If you can't return them you could try them and check the datalogs and the plugs themselves to see if there is any indication they are too hot.
