Will Hot Tank Remove JB Weld

My buddy's la 360 needs some help. Looks like the previous owner attempted to screen the block himself and it's a mess!!!!! Guy globbed jb weld on top of the lifter valley and the screens are cheap and ready to fall apart. Needless to say we r disgusted. So much for the block is ready to race:mad:

Only thing I can think of to fix this is to get the block hot tanked. Will that remove the jb weld?? Honestly dont know. Also he did the red paint inside the block. I'd assume machine shops would still take it to hot tank correct?

Thanks for any advice!!
