I recently got this H22 shortblock from a buddy. Sleeving was done in 2007/08 and I can't ID these. Anyone know what kind they are?

Thanks

 

Better angle

 

Older golden Eagle sleeves. Before the Godzilla Sleeve. Circa 2004-2007. I have that myself right now O-ringed. Having it bored to 84mm this year..

You're thinking of the newer (at least to me) Gozilla sleeve





I thought you were going to make this difficult.

 

Ahhhh! I was right. They are GE sleeves. Thanks Mac for the confirmation. I knew you'd show up and save the day ��

 

Better to have the block or head oringed?

 

It's a preference. Both work. Easier to change the o-ring in the block than the head from my experience only.

 

So the application process is easier on the block. Or are you saying after install

 

Well, GE puts in the original groove and copper wire. It seems to be easier to replace that wire on the block than the head. I was looking at replacement difficulty when needed.
