I know which side goes down, but on one side of the guard there are the letters "ADD". I was wondering if this goes on the exhaust side or the intake side. Or does it even matter? Both sides look identical.

I was also wondering if there was a special way to install it. Do you just put it in there and tap it down with a rubber mallet or something?

 

So does anybody know if it is supposed to be just tapped in with a mallet? Or some special way to do it?

 

please search
if you search you would know that most people do not recomend block guards and if you really want to install one you need to take you block to a machine shop and they will weild it in in a few spots

do not ust tap it in with a hammer!!!!!!!!

 

mine (KMS unit) was lightly tapped in with a rubber mallet, then used a punch to have it a little lower than the deck to aid in cooling the top of the sleeves (about 1/4 to 1/2" is enough) now once the guard is in, have the block honed or checked to ensure that it's not out of round. once done re-assemble.

after mine was installed the block was bored to the size of the new pistons, I have not experienced any overheating, or any drawbacks from having it installed.

 

nice pic i bought the same block guard, guess i'm gonna have mine spot welded and then honed
