LS3 head gasket thickness
You might see 1-2 degrees more timing (maybe) with tighter quench. Or less prone to detonation in August. I've had builders recommend them. And builders not.
I run them on my current motor. And plan to on the next. But I don't think it's a huge difference.

But if you go to 12+:1 scr, I would say that optimizing quench becomes essential to reducing the likelihood of detonation. With optimized quench, you virtually eliminate detonation as a potential 'problem'.
But hell....what do I know. I've only racked up about 40 passes and 12,000 street miles on my 13.3:1 scr Impala SS.....
Yep.

Mmmmmm.......11:1 scr (or 9:1 scr) won't benifit a whole lot for the optimization of quench.

Lots and lots of non-Pro-Stock cars spending money for 5hp... Everyone from hon-duhs to ZL1's... With everything from cold air intakes to titanium rods/valves... And these are all street cars. You don't have to be a NASCAR driver or an astronaut to appreciate a more optimal setup.
I don't believe you.

If you were in the market for headers, and the price difference between the 1.75" primaries and the 1.875" primaries was the same price difference between the .050" gasket and the .040" gasket, you would gladly pay the extra money for the larger primaries without hesitation. Why?
Because they are better, right? So why not pay the extra money for the better head gaskets? Sure,they don't give you the same results measured on a dyno, but you are paying money for a better, closer to optimal, part. Yes, closer to optimal generally costs more. A better eraser costs more for a kindergartener, too. This is the world we live in.
By the logic of the money could be better spent elsewhere, we all waste all our money that isn't spent on a good turbo kit and an arsenal of spare unmolested 4.8's... Because all that money spent on more optimal displacement, or more optimal rectangle port heads, or more optimal fast intakes is all a waste when we could have bought unopened junkyard motors and better spent our money on exhaust or tires.
Sometimes you have to pay to do it right. But you usually only have to pay once if you do it right the first time.

I see your point, sir. For sure. I've just never thought that head gaskets, even the closer to optimal ones, weren't going to break the budget one way or another. Stop smoking for a week. Buy one breakfast sandwich instead of two. They aren't THAT much.
All I'm saying is if you're on a budget, there are better things to spend your money on. If you're throwing down on a high dollar build, by all means do what makes you happy.
....... I mean, I look at optimized quench as much as an insurance policy for my 'high dollar build", as anything else. A matter of perspective, I supposed.KW
100% agree. It's almost completely subjective. I get to build and machine my own stuff so I can cut the deck to optimize quench. Unless I need to run a cometic, GM gaskets till I die!! Haha
