will it hurt. whats your opinion

You guys are getting way off course here. My question was what are your thoughts about using a ridge reamer to cut the ridge out. I was told by a friend who used a ridge reamer that he lost compression I guess because he used the reamer and apparently he didnt use it properly. Is it necessary to cut the ridge and will the new rings hit the ridge if I dont. I am not decking the block. The head is in the shop doing the valves and I am only shaving the head just enough to true it up.I done my 76 engine the same way 6 months ago but didnt have any ridge to cut and it runs fine.
