cometic vs. felpro head gasket

Jungy · 09-15-2008

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.

We use a lot of Cometic gaskets and assuming the block and head are prepared accordingly we have had very good luck with them. If you go with Fel-Pro I would look into the PermaTorqueMLS gasket. We recently blew a Cometic in the RX7 and went with this, so far so good.

This is 420a right? Not sure if that makes a difference on the answers people may give.

Is the OEM replacement headgasket that bad, why go to MLS? 22psi isn't that much really if you're using ARPs.

Isn't Rau still using a stock felt HG?

The stock head gasket for the 420a is mls, i've actually heard that felpro makes the oem head gasket for the 420a.

Rau has been using the PermaTorque MLS gasket for a while now, it seems to work quite well.
