440 leaking

do all of the header bolts go thru water jackets? how should I have prepped them?

On a lot of heads yes. I use permatex #2 on the threads.

Used the same on my old 440 with super comps, never leaked

Thats one thing about Permatex #2, you can apply it to the threads and insert it whether it's wet or not. Preferably dry would be better. Blow it out with a air hose. Spray some parts cleaner in each hole to really dry.

Good luck
