Head Bolts Size for 2G?

[DeNoZZo]

Can someone please tell me what the correct size of the headbolts and allen looking bolts are, what kind of socket I will need to remove them, and what the sequence for removing them is? I have searched but most of the posts that I have found are all for 1g, and don't give clear answers.

Thanks!!!

2g's take a 13mm 12 pt socket for the headbolts. The removal sequence is the opposite of the install sequence. Start at the outside and spiral inward.

What about the 4 allen head looking bolts in the center?

Those aren't head bolts. Leave them alone.

I've never been curious enough to investigate exactly what they are. But I assume they are plugs for oil or coolant passages.

if it is the large looking plugs between the spark plug tubes you are referring to.. they are core plugs, it is how factory got the sand casting out of the coolent passages when the head was first cast.
Just leave them alone if they are not leaking.
