Edmunds heads
 

Just picked up a set of edmunds heads and intake. Never installed aluminum heads before 47Ford. I'm going to get the heads checked but is there anything different about installing them ( head gaskets or mounting nuts or studs ) Thanks

there was a good thread on this a while back but i don't know if it was here or on the hamb. do a search and see what comes up. on mine i didn't do anything really different except i used the chamfered washers on them, without the o ring and they didn't leak for as long as i kept the car.

If they're anything like the Weiand heads I've just bought for my 47 engine, you'll need to put the long studs in, and use hardened washers.

As well as the above information, use composite head gaskets, and liberally coat each head stud with nickel based antisieze compound to help keep electrolysis at bay. Use a 50/50 mix of coolant to also assist in preventing this.

I use metal head gaskets with my alum. heads and coat the head, both sides of the gasket and block with copper coad spray on sealer. Have not had a leak problem. I use a sacrificable anode in the rad also. My experience with the composite gaskets is that they are a real pain to get a head off from and a mess to clean up after.

I believe stock studs work with Edmunds …. just like they work with the street ("S") versions of others (Weiand - Edelbrock .....................) its the race ("R") heads that need long studs.

I posted this before but I guess it didn't go anywhere. These are direct replacement heads of hi compression (8:1). They have a relocated spark plug that allows the use of a power tip plug, for better combustion of a lean mixture. Thes castings are quit thin so don't expect to run a high lift cam with out running into water. Great heads for a stocker.
The intake works best with 2" risers, better throttle response. This is a good combination with the right ignition system, a crab dist in good condition is about the best you can run is the early engines and a converted GM with Vac in a late engine. Good power, great mileage.
