The hottest part of the sleeve is the top(where the combustion occur)....let some space for the coolant to cool down the upper part of the sleeve.....I'd say something like 1/2 to 1 full inch below the deck.....not to far or you''ll have problem to weld(lack of space)....
I'd weld only the outside of the block guard, not the inside(sleeve side)
Someone correct me if I'm wrong.....

What is the brand of your block guard?

 

I got a JG block gaurd.. I also agree not to weld on the cly. but where on the block? in 4 corners? or the outside of the block of each sleeve?

For any one who reads this thread for a reference rep me

 

the correct way is to sell your block guard and save your $$$! i kid...but
the problems they can create for what little they do are not worth it imo

the aluminum has a different expansion rate than the sleeves they are supposedly strengthening when brought to temp. two metals expanding at different times doesnt sound like a good idea in your engine...especially so close to where combustion is taking place

just food for thought! good luck either way. they can be done correctly and that info is here but i would re-think the idea

 

Really? a 6 year old thread bump for that? Neg rep.

 

holy 06 batman

 

I think they figured it out by now, its been 6 years

 

if I was playing COD, XxTACTIKZxX, would be one of those dbags running around no scoping.....just sayin
