x2 on the Victors. Definitely replace your TTY ( torque to yield) stock headbolts as they have probably stretched. If it's truly built they should have used some ARP hardware.
The best head gaskets are the ones installed correctly that won’t leak compression or water . just about every gasket will work perfectly fine if the machinne work is done correctly the head is re torqued after the first heat cycle
Why is everyone always so quick to blame the machine shop? If the machine work was that perfect you wouldn't even need gaskets.
Most engine failures after a re-build are the result of improper break in.
It's cheap parts, crap gas and a heavy foot that causes most failures.
Re-torqing head bolts on domestic engines is a myth. In most cases major disassembly is required to access head bolts.
I'm a diesel tech at a Ford dealer. The 6.7L powerstroke has 45 head bolts. It would be 10-12 hours of work to re-torque them. And they run double the compression and more boost.
Engine break in is a myth.... Surly has nothing to do with blowing a head gasket....
Engine break in is supper critical, if you want your engine to last more than a couple months.
Head gasket failures are due to knock. Plain and simple. Overboosting with the wrong fuel and too much timing. And the operator not having a clue about what's going on. Most guys can't tell you how much boost they are running when they have a gauge right on the pillar...
Basically what I just said.
MLS gaskets are the most durable head gasket you can buy. Will others work? Sure but they will blow way before a MLS. Guaranteed...

I agree with ya BUT if the guy is having problems with the car (tuning ;-) ) he should use a stock type gasket .. It's very forgiving till he has the car figured out. Of course get rid of the "O" rings to.
I'm not looking to start another break in debate... I have my ways and they work. For those who think it's not necessary, I almost always get paid to do their engines again within a couple months.
