Yea it'll be fine

 

ok thanks for the quick reply! im really hoping i dont get a broken bolt

 

Yea I hear ya. The most famous one to break is the driver's side closest to the firewall so be real careful. My front one on the driver's side was broken before I ever started lol. But when I swapped heads they're all there.

 

do headers usually come with new bolts or do the stock ones get reused? my tahoe is a 2000 and i was surprised to see that all the bolt heads are still there

 

Yea my truck is an 01.

As well known as the bolts are for breaking off, I wouldn't recommend reusing the stock ones although technically it can be done if they are still intact. I used ARP header bolts. They are like $40 iirc

 

I soaked my bolts for about a week with PB Blaster while the engine was hot. I sprayed them and drove it some more and resprayed. I used an air ratchet with low air pressure to brake loose the bolts. I didn't have any trouble with any breaking. The driver rear bolt was a pain to take out and put back in. I used stage 8s.

 

do you guys know what size bolts and length they have to be or are all header bolts the same?

 

8mm x 1.25

 

All of the bolts are the same.
