I've got a piped 700 and blew PTO due to heat....and jetting. what is the best aftermarket head gasket out there....

Opticool... don't know of any others?...

Also will an SRX rear heat exchanger work on this machine?

Think i found out why it blew as well..... first the vacumn lines into the air box were plugged in which I ignorantly did when i first got the sled after cleaning the carbs.... had no idea this had such a huge effect on the jetting... I guess it caused my PTO cylinder to run way to lean.... and secondly my buddy filled it up with regular while I was in the washroom at the gas station, he felt like an idiot...
