Working on my 62 Lark 6 cyl. Heat riser was stuck. When purchasing the part, I go both the exhaust and intake manifolds along with the heat riser as one. I have removed all of the old parts off of the motor. I have cleaned up the areas where the new gaskets go with a razor blade very, very well. In putting the new manifold gasket on and the gasket to the exhaust pipe, do I need to apply any sealant? Please advise, thank you.

You should check the mounting flanges for each runner of the intake manifold on a straight flat surface (or with a good straight edge).
These manifolds tend to warp a bit between the intake runners and the exhaust runners.
That makes the gaskets on the 'low' runners see less gasket squish pressure, and an increased chance of an intake leak...
I spent $75 having one machined flat to get it to work right without leaking.
The next one bench checked out high and low on opposing runners too. I took a belt sander to he high runners (carefully, mind you;)) and the manifold fit beautifully and worked superbly...
Cost? 16 ounces of cold adult beverage pleasure....
