trying to make this short and sweet. Not gona save the block but would like to take my b16 head off my b20 block.....anyway. These hex head bolts are a pain my @$$. At first I thought they were metric. nope. 3/16. so at first I tried to use an allen wrench and pliers. (knew it wouldn't work). thats all i had. The head bolts destroyd/rounded off the allen wrench.
so next step. I got the hex socket from autozone. (no it is not a 4mm, 5mm or 6mm. tried those). Same results, rounded of the hex socket.
I will go to Sears and try a craftsman one next. This really sux cuz I live in bfe and got drive 30mins to sears. anyway. The bolts aren't stripping, its my tools. any insight or any comments thanx.

 

About 62lbs.

 

I'm pretty sure its just the cheap tools im using. If it tears up the craftsman then I wont know what to do. Is there anyway it could be a 4.5mm? the 3/16 seems like a very good fit. the 5mm is too big and 4 mm is too small

 

um, sounds like you have head studs. use a 12pt socket to take the nut off.

 

Damn you JDogg ur making me look like a retard. just took another look and yep looks like im gonna get the 12 pt socket and take it off. lol.

 

is that a 14? dont have any 12 point and will have to buy one

 

lol, it happens to the best of us

i'm pretty sure its a 12pt 1/2 inch socket you'll need.

 

12 point 1/2" deep socket 1/2" drive with a long breaker bar will get those headstud nuts off.

 

jdogg and vtec.....you guys are rights. wish i would have loosened the nuts with the motor in the car. will remember that next time. thanx guys

 

i thought they were 9/16"? that's what they are on my H, maybe B's are smaller?

 

h22 uses a 12mm stud, b-series is 11mm
h22 arp nut is 9/16

 

I'm gonna try to post pics because I got cracks in all 4 cylinders! sweet. time to sleeve the b20
