I like the gasket, it seems to be a quality product. However, as expected, it is MUCH thicker, about a quarter of an inch. That's good and bad: Be careful when fitting the Triple Check to make sure there aren't any leaks, as it's so thick it's easy to leak if it's not perfectly aligned. Also, it becomes a nightmare when you have extra room above the valve cover, so make sure you have room. I had to install it 3 times due to leaks but now it's perfect and seems like a long lasting product.
