428 cobra jet head shims

By jim - 09/25/2005 10:20:00 PM; IP 142.165.184.56

I purchased a mustang with a 428 cj a few years ago. The car runs very strong but the compression is higher than I am comfortable with for street use. The heads were milled however I am not certain of the amount they were taken down. Has anyone had any experience with the .0020 CJ head shims which I believe are offered by Felpro. I thought this may be an option rather than finding a new set of heads.
Thanks - Jim
