Aluminum big block cylinder heads

[BSB67]

If he's already got 2293s (original post said TRW domed piston) and he wants it to run on pump gas with that smallish cam..... op better do some calculatin' to figure out what compression ratio he wants. That will determine which heads to look at.
My suggestion would be the open chamber rpms.
(I have 2295s domed trws in a 440 with iron heads, and it will run on 91, but it has 40 more degrees of cam than the op, and lots of converter and gear, and I still add a bit of 100LL cause I can).

Yep. The details will matter

What is difference between the Edelbrock EZ street vs the RPM"s?

Rpms are supposed to have better quality valves and springs. Other than that..... a couple of bucks.

Valve seat material is different too.

Streets come with a warning not to go above 5500 rpm. I do know people that cross the line in a bracket racing , but I've seen enough sideways valve heads and total destruction that I'd be reluctant to push any kind of luck and listen to what they said.

Yikes.
I ran my iron head 440 to 6200-6400, before I found out it ran just as quick and fast shifted at 5900.
I guess it's good that I bought rpms (and maxwedge victors!).

Is this a Wedge, or a Hemi?

If it's a wedge you can't use that cam, as it's ground different.

Wedge and Hemi cams are not the same.

It's a Mopar Performance purple shaft street hemi grind for the b/rb engines. I don't remember the part # but I could probably find it in my old catalogs.

I am looking for a pair of aluminum heads to put on my .030 over 383, it has a 284/484 street hemi purple shaft cam and i'm going with TRW domed pistons. I had 3 sets of heads that were stolen from my garage. I was going to use a pair of Stage 6 heads I had. These are about impossible to find any more. I really want a pair of raised intake port heads but I'd settle for stock port locations for this engine. Leaning toward the Performer RPM heads at this time. Anyone have any recommendations?

I ended up getting Edelbrock 77929 Victor heads. I'll use them on my 383 first then eventually they will go on a 400 based 500" engine. So all the 440 intakes i had are sold since they won't do me any good.
