I know you said that you are on a limited budget but since you are going to a 390 I would weigh the cost of buying aluminum heads against the cost of rebuilding the cast iron ones.

I will look into that. I assume Jegs or Summit or cj pony. Any other suggestions?

I would say Summit or Jegs would be the cheapest but there may be others I'm not aware of.

I agree with John.

Even if you need to wait until you get the money, aluminum heads are a 'must have' for any 390 build for a host of reasons.

Heads are the heart of every engine and one you do not want to cut corners on. Used heads will need all mating surfaces decked, exhaust valve seats milled and inserts installed, valve guides need to be serviced, new stainless valves installed, a valve job to mate the new seats with the new valves (useless) umbrella seals that might fetch ~$300 per set in the aftermarket arena.

Edelbrock performer rpm aluminum heads are lighter but they transfer heat four times faster than iron. They come with all new bronze guides, hardened seats, stainless valves, springs and the threaded holes have helicoil inserts. Used Edelbrock aluminum heads fetch over a grand per set.

To me, this is a no-brainer. Remember to calculate your new pistons in conjunction with the head's 60cc combustion chamber when you choose your desired compression ratio. - Dave

I have been searching the web for aluminum heads for the 390. This is an assumption on my part but I assume I need to use my exhaust manifolds. If so I have only found 2 heads with the bolt pattern that matches. One is the Edelbrock 60079 at $814.99 each and one is by Bearblock at $2,450 a pair. Are there other options? I am not against the #1,600 for a pair from Edelbrock. But there are numerous heads available for the "Mustang" type exhaust bolt configuration.

You have done well to find assembled Edelbrock FE heads for $814.99. FE engines have been out of production for many decades but SBF engines are still fairly recent. Supply and demand still rules as more cars on the road are churning SBF engines than FEs. - Dave
