I am not a pro engine builder by any means, but I have put a few together. I have never had a problems with a front seal leaking on any of the engines I did. After much research on the one piece front seals (use lots of rtv to anchor them in the pan), I decided I didn't want to use them.

I have found that if you are careful and use the kits that come with quality gasket kits, rear seals can be leak free as well. I did have a few leaker back when I thought I knew better than the gasket manufacturers.
