just while you have the head off take it to clearwater cyl. head and get 25k shaved off it and pop it back on...it's very light head work but a nice diffrence and cheap as well if you try and get a gasket to raise the comprestion you will spend more than you get out of it but with a simple shave of 25k you will put your cyl. psi at around 200-210psi per cyl. you need to have the head decked anyway if it has had a blown head gasket, and let me be clear you dont have to get it decked but it's a good idea to,
so in short it's a good idea to get it decked and while it's there i would get it shaved 25k while it's off you know....
