what exactly is so special about this headgasket? i've checked out the website and it doesn't say anything about it. thanks in advance!

 

they use a metal plate 3mm thick between 2 factory honda gaskets. it lowers compression about 1 full point.

I have run 13-15psi for 6 monthes no problems on a 84k mile motor, I might be keep that set up one more summer

 

how much do these run? i checked website but there is absolutly no info on this stuff. also, do they have a bockguard?

 

they are about 350 bucks and money well spent. yes they have a block gaurd that I also have. the head gasket block gaurd set up has been tested to 22psi. the best time run on one with stock internals was a 11.2 and that was with the fuel system jan and I ran last year with stock ecu.
