Head bolt way too long
Hi everyone, I was I the process of installing my heads and my bolts all bottomed out with about 2 to 3 inches from the head. The holes are clean, I chased them and also measured with a thin tig welding rod and all the bolts came up equal length at around 4 inches (don't quote me on it) it's a 5.7 ls1 block, unsure of year but I thought it would use the same bolts that I use in my 5.3's (very long). What bolts do I need? Looking for arp brand. Thanks, any quick info will be appreciated so I can over night some. Thanks again

Did some measuring. Here's what I found
This is one of the shorter outer bolts, the orange line on the left is how long the bolt is when torqued all the way down in the hole. I measured 2.75 inches from the block deck to the bottom of the hole. It was 2.75 inches deep in every single hole, the inner ones and outer. Im kind of confused. Any ideas?

I just measured the depth of the holes, every single one was the exact same as the others, so that leads me to believe that there are no broken bolts, debris..etc in there, so I'm stumped at this point. I've never seen anything like it. No one has ever had an issue like this before?
