What''''s up Regal fans,

Wondering if anyone out there has had head gasket problems after installing smaller pulleys? I''''m about to go down to a 3.4" but am concerned as I''''ve racked up over 100k in miles. I''''ve heard all the warnings about trashed blower bearings when using a standard puller, so will do this right, with a good tool....but I don''''t want to have to do a major gasket job after throwing down a couple hundred in blower parts for a couple extra psi boost.
Comments?
Thanks.....Kawrider
