Quick and Easy Question I have a 99 trans am and over the weekend I am going to be doing a head gasket replacement. I am wanting to mill the heads . 030 but I'm afraid out might conflict with my cam. what do you guys think? cam specs are .220 .228 .598 .598 with a 114lsa.
It's a pretty mild cam by today's standards. As HCI2000SS said, there should be plenty of room left if you are going to be using stock gaskets as replacements. While you have the heads off I would suggest replacing the lifters and trays. And if you have the cash and time some hardened pushrods and rocker trunion upgrade are always good to do as well.
The only thing you will need to pay attention to however is if you have 853 heads, some of them have a notch on the head and if yours have this, you will have to make sure whatever gasket you use has the provision for that notch or else you will end up leaking coolant all over the place.
Here is a pic I found of some 853 heads. The top one has the notch I was referring to and the bottom one does not.
