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

I used FelPros marines on my heads.Mine were the first sets.Id have the valves checked because the valve job is OK but not great.Mine needed lapped.What cam are you running>My .588 we upgraded the spreings retainers and locks.Went to 10 degree pieces.With a smaller cam and auto they would have been good to go.Never trust an out of the box part.Mine have been on over a year and no problems.Rocky

Some guys will reccomend high dollar Coemtics, and race gaskets. I reccomend the cheap FelPro PT gaskets that you can get through Mancini or Jegs/Summit for $35-$40 a pair. They have a bore of 4.520 and hold up just fine. Matter of fact I have used these gaskets on 493 cubic inch Indy head engine with 12:1 compression and Alky. I even reuse them at least once before I toss them. If everything is nice and flat, Big block Mopars have a great cylinder head sealing design. Here they are and $17 each. Now worries with overhang with these babies. http://chucker54.stores.yahoo.net/felbrbenper.html

I'm ASSuMEing that you mean stamped steel rockers when you say STOCK ? If so check and make sure the rockers clear the spring retainers thru the FULL RANGE OF MOTION , one person posted somewhere about an issue they had (droped a valve ??) because they didn't check .
