For a hot street car what heads would be better.

Edelbrock 60519 brand new $1600. Or Ka heads ported and polished by Joe Mondello $800 used? The bottom end would be pretty much stock with a agressive but streetable cam and edelbrock performer manifold or maybe the edelbrock rpm air gap. Compression between 9.5 - 10.1. Also is there anything different about Ka heads being used in a car?

The Edelbrocks would still be better.

Thanks for the reply. Do you have a link or part # for the cheapest rockers and rods that will work with the e-brocks? I guess best bang for the buck type thing. Thanks again..

The Edelbrocks like any aftermarket aluminum head, needs to be checked out before bolting on. A friend just bought a pair and the chambers varied from 77-81 ccs on one head. That head wasn't flat either. This probably wouldn't make much difference on the average street motor though.

I had posted about some new Mondello heads a little while back - maybe chinese, but would save a few bucks for a street motor! Includes intake, too.
Punch Mondello in the search area.

They're from Procomp, just contact them directly, they'll put you in touch with one of their dealers.

You may save money with the edelbrocks compared to fully working a set of irons (valve job, surfacing, guides, etc.). However, you can run stock rockers on irons, but need roller rockers and studs on the e-brocks. It also seems easier to seal iron heads to the block. As for flow, if it is a street engine and cam, you probably won't see much difference. If in a cold climate, remember the edelbrocks don't have heat risers.

How would these heads compare to the edelbrock heads? They are much cheaper.

Those are the Procomps I just spoke of.

Al2011

You're right I apoligize I missed that. how do you think these are compared to the e-brocks both out the box?

Bernard Mondello Racing Engines has a thread on ROP and offers them in three stages of completeness, starting at $649.

citcapp

That's per each correct?

cutlassefi

No, a pair bare.

I looked at the sales add for ROP members only. Great pricing, this might bring down the cost of the brock heads. I wonder if the fuel pump clears the procomp heads. I got kicked off ROP so I don't cualify for the special price. Don't know why I could not get a mod to answer me.

380 Racer

I bet if you talk to Benard, he would sell them to you for the same price.

Al2011

I'm new to this site. How do you get to ROP to see these heads. I've been searching all day.

I just read the post where the combustion chambers varried from 78cc to 81 cc in the same head and that the heads were not even flat. I must say, I'm not surprised. My brother and I have been purchasing Edelbrock equipment since the later part of the '60s, and back in '70 f/ example, a time I remember so well, when my brother had a '58 Corvette w/ a 327/365 in it, he bought an Edelbrock manifold. The finish on the manifold was nice and clean, w/ no seam showing/left trash on the surface that should have been ground off. In those days, the Edelbrock manifolds were very pretty looking and also performed well. I recently bought an Air Gap manifolod f/ my '81 Corvette. After opening the box, I called my brother back home and told him how dissatisfied I was w/ the finish on the manifold, so many places that should have been cleaned up but were just left, looking like a mess. I was pretty much bumbed out. The quality control department there at Edelbrock is hurting IMO. Where is the pride in the workmanship? I personally like things that run to also look good, and Edelbrock has forgotten to take care of their customers to do w/ their components not just performing well but looking good at the same time, and to do w/ the heads, not even being precise enough to maintain constant chamber size across the board. Come on, Edelbrock, you claim the old "made in the USA," how about making the good old USA look good w/ what you turn out, don't make us all look bad.

Al2011

So in your opinion would you get the procomp heads or the edelbrocks?

cutlassefi

What's your budget?

Imo the Procomp heads along with an Edelbrock Air gap RPM with a good 800-850 carb, 10.0:1 compression and the right cam will get you 450+hp and well over 500lbft of torque, yet still be very streetable.

Again jmo.

I'm just doing it a step at a time. This weekend machine shop will eat up $700-1000. Then I will do the summit racing finance thing for a rebuild kit or maybe even piece a kit for myself about $600-1000 before end of this year. Then January (tax return)I should have my mind made up between edelbrock or procomp heads the Mondello worked ones, E-brock RPM Air Gap, and E-brock or holley 750 - 800 cfm carb, Hooker headers and misc. parts to dress up the 455. I will leave the cam choice for a reliable source. My compression should be 9.75 - 10.0 With 15cc dish KB pistons or maybe I may go forged because a friend of mine wants to install a nitro kit. If anyone has any machine shop tips or anything I may be missing let me know please.

380 Racer

Mark......just curious, anybody running these heads on a running engine? Either on the street or down the track?

cutlassefi

Not that I know of but I bought a set that I hope will be on a SBO stroker before next summer.

380 Racer

OK.....thanks.
