Yea, everyone hates block guard because they don't allow for enough cooling of the head, but actually take a look at the golden eagle block guard...http://www.accountwizard.com/clients...tem&itemid=128...and tell me what you think of this design. Will this still be junk? Would filling the block be better?

 

those block guards have a better design. you should be ok. you can double check with a head gasket to make sure the coolant holes are not blocked.

 

But is this going to be anymore benifical then block filling?

 

my b18a had a ac block guard. from what i hear they don't have that many problems
