Head bolt thread size

[SmoothCustomer]

I'm looking for the thread size of the head bolts. If someone could let me know that would be great!

 

Are you talking about the bolts that hold the head to the block?
If so, then it should be M12 x 1.25 for a 6 bolt motor.

Yeah that's what I'm looking for thanks. Do you happen to know the thread size for a 7 bolt while you're at it?

 

^11mm 1.25 I believe

 

I'm pretty sure that's right. When I looked it up on google and dsmtuners it said that 6 bolt are 12 x 1.25 and 7 bolts are 11 x 1.25.
but since I don't have one on me right now, I can't prove it without a doubt lol.

That's correct - 11mm for 2G. Not sure about 1G 7-bolts, though. They might still be 12mm. Pretty sure all 1G heads have wide bolt holes.

 

1g 7 bolts do use the smaller 11mm bolts for sure. I used a 94 plymouth laser turbo engine in my first swapped colt and it had them.

 

There ya go! if you're looking for a set of bolts for a 6 bolt, I've got a set of used 6 bolt ARP studs.
I'll be honest, I bought em a while back and they're still in the unopened box cuz I didn't know my car already had them when I did the head swap, so I'd have to make sure everything's there and all good first.
