Trick Flow small block heads

No leaks. Held a vacuum and pressure during mock up. No leaks on the Dyno! I did copper seal them though, just personal preference.

Glad to hear they are working out. I used hylomar around all the water and oil passages on mine. Like you said personal preference and hopefully cheap insurance. If I may ask what convinced you to plumb to the side of the block?
