Don’t use if you have hard to reach header bolts. Also the washers provided are super thin almost not with using

So i had some other bolt on my headers that just didn't really seal good the header and gasket no matter how tight i would tighten them. I found these bolts. Man wish i had found this first. Game changer. All i had to do with these was shave a little off the heads and screwed right in and actually felt good with them! No more header leak at the block.

I get that some headers might make it difficult to fit a traditional hex socket on a header bolt, but I don't understand why these take a hex key. Makes it so much more tedious than it needs to be for install. Just make it a regular bolt.
