Ok folks

I'm getting ready to swap over my well used 346 heads to a set of 440 source heads.

Here is the engine
440 engine with edlebrock ch4b intake. 770 street avenger carb. Hedman 1 3/4 headers

What are the best gaskets to use when changing over to the aluminum heads?

Can I also use my stock rocker assembly or must I get adjustable ones?

I'm really excited about this change!
Mike
