Whats the part number and where can I find them?

I believe these are what I have.

Any reason why you went 12 point over 6?

 

I have them also. 12pts because you can grind down 3/8" box wrench and still put it around the entire head of the bolt. I've use those exact bolts for several year now and many header removals and never had a problem. I just put them back in my new motor.

 

If I were to do it again I would get the Breslin bolts. They have a a spot in the head of the bolts for an allen wrench. Anything that gives you another option for tightening those bolts is like gold in these engines. Just a thought.

Gives you more angles to work with, you really need it in an LT1 engine bay.

 

The 1" bolts won't bottom out?

--it is part # 070-400-1110 that i used

 

But what about the part number 070-400-1210?

Those have the 5/16" head, 1" length and 12 point head, and it's cheaper, wouldn't that be the best combination?

 

those would work fine too. i just posted what i used. i didnt like the fact that i would HAVE to use a 12 point. i like options

 

any reason you guys are buying 16 piece kits vs. the 12 piece kit? Do you all have big block heads?

 

The bbc kit I posted is cheaper, maybe that's a reason. Then you also have some extras just in case.

 

yeah the only reason is price. I have actually bough this same set several times for a few friend who I have put headers on for. Now I hav an extra set of 12
