Probably the best fix would be to mill the head as needed to remove the grooves, about . 020” to . 030” deep. Use the 3283339 gasket which is . 020” thicker, either a stock gasket or a Haisley gasket. It is OK to sink the valves a little and to reface them to get maybe another . 010” valve inset. Stock inset is about . 050” to . 055” from the head surface. If you choose another fire ring gasket, get the grooves cut to meet Haisley's specifications. I suggest Kells Automotive in Las Vegas since you live there. They also know how fine a finish you need on the head surface. Most shops use far too rough a surface finish.

Thanks for the reply Joe. Unfortunately it is in the original shop to get fixed. He did however Talk with Van at Haisley to get all of the information and specs very similar to your post. He also got a new fire ring gasket set from Haisley. Van even sent him a new cutter for making the grooves. I hope all goes well as we both know this was a very good head before it got machined wrong.

Hope it works out to your liking. I thought I was the only guy who had bad things happen...
