why are blockguards bad?
 

some people seem to love them, others hate them....why?

Re:why are blockguards bad?
 

Im not sure, but I read somewhere that you have to heat the block while installing them in order to keep from damaging it. That might have something to do with it, and maybe that some people feel its only a bandaid if you will.

I would rather lay my nuts on a hot stove while getting my nipples pierced with a steak knife than use a blockguard in any of my motors.

I had a bad experience with them and I don't care to talk about it anymore. >:(
