I've used the sce Titan coppers with no issues. I started off with cosmetics and kept pressurizing the coolant system. Went to the coppers and never looked back. Even had a few mistakes happen while running 30+ psi at 6500...never blew a gasket....cracked a block from a series of violent pops...but gaskets lived lol.
If cometics are blowing, there has to be other problems.
pull it apart and break out the straight edge and some feeler gauges....
Wow...definitely not an issue on how the engine is setup then. I've seen rpe's work first hand and its definitely top notch. Maybe you have an issue in the tune? Is it the same hole each time that's causing it? I've been working on a car that blew a cometic and it turned out #1 and #2 needed additional fuel added into those cylinders through the xfi. No knock was present in the logs either.Kevin, I used cometics on my original unprepped block and did the same thing, pressurized the cooling system. I had the new motor built and assembled at RPE. He knows what he is doing with these motors, I blame the gaskets. I run on the rich side with my AFR and see ZERO knock. The cooling system is pressurized again and leaking compression between the layers. I will check into the Titan coppers. Thanks!

I went through a set last year, but the car went just passed the 1/8 mile running 12.7AFR, and then 11.7AFR for 6 runs. I was also running the 4.0x bore gasket on a 3.82 bore. This year I put a fresh set of 3.84 .040 gaskets on and saw some lean conditions when low on gas, but let out. I have run 9.86 with them and they are still going strong. I keep the AFR 10.8, 11.0 at the leanest running 23psi. I have seen 29psi only running 110 (which is actually 107) on the street tuning with no problems. At the track I am using Q16.
I think you are having other issues.
As a side note, we have had bad luck with the SCE titans on 8 bolt blocks. I guess use what works for you.

Are they being installed dry?
What is going on with them now? Pressurizing the coolant system again? Or?
Did you retorque? I retorque the day after, and then after afew easy heat cycles (no boost). My first set wasn't retorqued after a heat cycle. After I noticed a problem, I tried and got 1/4 to 1/2 turn but did not fix the problem.
