LA360 compression
BUT remember, unless the block's been decked, it's very likely tall from the factory so that will lose a little more compression. I still stick by my original recommendation. Build it with the aluminum heads as is. Just because everybody on the forums and magazine articles run them with compression on the ragged edge doesn't mean you have to, OR that it's necessarily a good idea. But, you HAVE all the parts. That in and of itself is the biggest decision maker to ME. It's your project. Build it like you want to.
