im not sure what the epoxy temp range is, but im not too worried because if the blower temp ever goes above 400 *F then there is something wrong. it is machineable, i was able to easily cut it down with a die grinder. it is easier to grind off then the actual blower case.

if it drops out then oh well, i get to rebuild my bottom end again (with a cam). other people have done RTV and it has holded, so i trust that this will stay put.
