What is the benefit of a block guard? and is it really worth spending the $$$?

 

no.... the proper way to use one would to be to have it installed and then have it bored/honed to make sure that everything is inline and rounded

 

x2 and i would also have it decked depending on how deep they sit, i got sleeves and no nothing about the block guards expect they arent a replacement for sleeces and dont really help the structural integrity of the cylinder sleeves, as the sleeves are still aluninum and not ductile iron like aftermarket sleeves

 

Simple Answer... None
DONT wast your money!

They're designed to keep the sleeves from shifting, but often times starve certain areas of the sleeves of coolant causing hot spots and other issues.

Some people swear by them, others will never use them. If you put it in, make sure it's done right.

 

I had mine professionally installed by a local machine shop, and have had no issues with it whatsoever.... They basically press it in with the same machine used to press in sleeves, deck the block, bore and hone the block and thats it... The block is still in my car daily driven making almost 600whp and beat on, on a regular basis... No issues at all...
