Edelbrock Heads

Does anyone have any experience with the Edelbrock aluminum heads for big block chevy? They say in the catalog that consideration needs to be taken as an open chamber style piston can't be used with those heads because of the spark plug location. I am wondering if a closed chamber style piston will work.

Yeah but I think there is a multitude of other factors to consider regarding piston design. Infomaniac can probably help sort it out for you better then me.

I will say that I used a set of Jr's heads on a 496 bbc blower motor build up for a friend and don't think I have ever seen a nicer looking cast aluminum head. The motor was destined for a show car so I was pleasantly surprised. I think if your going for looks, you cant beat Edlebrocks heads.

I've got a new set of Edelbrock "Rovals" for my '35-haven't used 'em yet, but I think they are 110cc chambers-aren't you looking for the square ports (RPM range 4500 and above)?

The piston mfg can tell you what heads they are compatible with.

The Chapman ported Victor Jr is available in rectangular or oval ports w/ 112 cc chambers which like the 110cc are "semi-open chambers". TRW has a piston for my bore but it is closed chamber design with a .474 dome which as far as I can tell will give about 10.5:1 with the 112cc chamber. Just wanting to know what type of piston others have used with the performer heads.

I have built several different combos with the Performer RPM head. Each one needed "massaging" of the piston dome to clear the chamber. SRP's open chamber needs the least cutting. TRW/Speed Pro/Manley pistons, 2307-2308 won't fit without MAJOR re-profiling of the dome. The closed chamber pistons would probably need cutting around the outer surfaces of the dome.

I am checking with SRP now. Thanks for ya'lls help! The TRW part numbers listed above show on flatlander that dome machining is req'd.

Built a BBC with the Edelbrock RPM heads and 12.5:1 SRP pistons (pn203433) last year for a customer. With the stock 119cc chambers the pistons required no work to fit.

Heres where things get tricky for me. I have a 402 with 4.155 bore. The only piston available that I can find is with a closed chamber dome. I am looking at the Victor Jr. CNC version with a 112cc chamber to keep compression up. I am waiting to hear back from SRP on their 402 closed chamber piston..............but I can get a custom set made for $685 to any specs and I'm guessing 8 SRPs are gonna cost more than that so.........the saga continues.
