Small block billet aluminium thermostat housing

Can anyone recommend a good/leak free one? The only ones I have found were on ebay, not sure of the quality of them.

Thanks

I've been using the billet specialties one - working good for 2 years now. O-ring design. Find them on Jegs & Summit (maybe E-bay too)

Yep, I use the billet specialties one as well. Nice piece, never a drop leaked from the o-ring.
