Relieving the head PROPERLY might be the method of choice in this case
I believe.
or
Use one gasket and buy premium
or
Price a good bare head from one a supplier or one of the Mikes out there
and swap all your components on to it. $$$
(Preferred, but most expensive choice.)
or
Try one of Stans spacers?????
or
Pull the pistons and take .020 off the tops (new rings too).
Decisions....
