Blown head gasket- Should I lower the compression when I replace it?
I have a b18c1 at 10 psi and hondata with 300whp. I blew my headgasket yesterday and will be replacing it myself in a few weeks. I am going to get arp head studs. What I want to know is should I get the OEM or Cometic head gasket? And should I buy a thicker hg to lower my compression? Will I need to retune my ECU after that change? Thanks

Either or doesnt hurt to do. Make sure when you head gasket blew that it didnt overheat or warp your head. But im sure it didnt. Find out your cause for the blown gasket cause 300whp on GSR shouldnt be happening.

I have been driving it at 7 psi with a fmu for a year and then another year and 2 months at 10psi with Hondata. I just figured it was getting worn out????

Re: (b18psi)
IMO, not necessary. You can always run a conservative tune.
My headgasket went cuz I overheated the engine at the track. Corrected the problem with a better radiator. Replaced my gasket with oem, added some arp studs and it's been runnin' strong since.

A blown headgasket is a damn good sign that the motor is detonating and he just can't hear it though.
