As far as the 8553 head gaskets I say to each their own but the bottom line is from what you have mentioned about your engine you should be looking at cometics for the correct clearance. My pistons were .017 average out of the hole and I went with these Cometic MLS Head Gaskets C5622-056 Probably not what you want to hear but its a worth while investment to know things are right.
On the contrary it's exactly what I want to hear. Understand they cost a little bit more but it's not out of the world. Never have had anything on the car that didn't cost at least plus half of what I paid for the custom part to put it in... lol..
