cometic vs. felpro head gasket

[Jungy]

So the story begins when I swapped out my crane 14 cams with a set of crane 16 cams. I replaced the oem lifters with stronger pt style sbi's, the oem rockers with the stronger 2.7 ones, I also figured I'd change the timing belt too while I had it apart. I went with a brand new timing belt from oreillys and it snapped after only 200 miles, bending 14 out of the 16 valves in the head. So now I am looking at getting some arp's, ss valves, and a new head gasket. I did some searching and didn't get any definite answer as to why one would be better than the other besides the cometic costing roughly $30 more, I mean they are both mls. I've been running 22 psi daily on e85, if that is going to make a difference, so I would like to get an answer on which one would suit me best.
