How do you seal your small block intake?

- still not sure whether I need to smear the RTV on top of the gasket around the coolant passages after the gasket is laid down. Please advise on that.

- also still unclear as whether I need to smear some under the gasket around the intake ports. I don't think I need to do this but please advise either way.

Do it now, or after it leaks you pick. :D

Ultra RTV blows in my opinion. (way too soft)
The hi temp I don't necessarily use because of the hi temp part but more for it's dried consistency.
The hi temp dries harder and is quite a bit tougher than regular or ultra. (a lot like Right Stuff)

Here's a mind blower for you that I never told anyone because I don't want their opinion.
I use the all metal intake gaskets with an aluminum intake and STILL don't have leaks.
One of reasons why is that the bolts line up with the holes better and the intake sits lower between the heads making that front and rear gap a lot smaller.
A thin film of RTV around all the ports of the heads and intake both and the metal gaskets only.
