sounds interesting. is anyone willing to try it? if so let us know the outcome. spare heads for these six's are cheap, especially in the unmodified state. it could just be the cost of gaskets and some time. i'd try it but my head is allready modified. i'd hate to cut the groove and then find it did not work on my head. i do have a stock six in a 65 wagon. i would be willing to do it to that. but not in the near future. tom
