Edelbrock E-street heads
 
Im doing a mild 350 chevy build and i have a set of edelbrock e street heads in the garage from a build i did a while back. Im going to clean them up a little bit and change out the valve springs i was told that the K-Motion K-750 springs were a direct drop in, anyone done it or know if it will work?
Thanks

I would use the springs that your camshaft mfg. recommends for thier cam and that fits the E-Street heads valve spring pocket.

Thanks for the info, yes i plan on porting them the runners are a little rough.

I will be home in a few days i will post pictures when i get them torn down and cleaned up and ready for porting. Was thinking i could soak them in varsol for a day then pressure wash them. A few guys i have talk to have machined the spring pockets to accomodate 1.46 springs. As for a cam i was going to run Howards retro CL110245 225/231 @50 500/512 lift 112 lobe separation. I'v herd the estreet springs are not the best so i will see what Howards recomends for springs with that cam. As far as valvetrain i was thinking roller tip rockers from comp or howards havent decided yet.

Long story short the engine is going in a 73 camaro. I had afrs on it before, then had a cam lobe go south. Pulled the engine out to clean it up and put a set of bearings in it, a friend of mine was in a bind and needed a set of heads for the weekend and couldnt wait, so he paid me what i had paid them. With house renos and everything els on the go I was thinking i could sweeten up the edelbrocks.

350 .030 over flat tops .025 in the hole fel-1094 .015 head gaskets edelbrock 7101 performer rpm intake, holley 670 street avanger, msd street fire dizy, 1 5/8 long tube hooker headers, 2 1/2 duel exhaust thrush turbo mufflers. th350 3500 stall 3.73 posi. My goal is a true 370 hp

I'm not sure is a 1.29 beehive spring will sit on the spring seat i havent got
the heads apart yet. I should have time on monday or tuesday as soon as i get them cleaned up i will post pictures . I will also post pictures as i am porting any advise would be much appreciated i have onley ported one set of heads 10 years ago in high school shop.

Sounds like a hell of a combo, i have a 96 350 vortec would i be better off using that block?

Got one of them cleaned up after work

theitalian 07-24-2012 10:01 PM

The easy off worked awsome but i seemed a little harsh on the aluminum

If you used the AFR 180s,that lith\tle solid roller,A 750 HP x pumper,you would probably have a real 440 HP engine.Put 3 inch exhaust system on it some day

Don't know if your interested or not, but I thought i might through this out there as food for thought.
I have a set of Edel. 6073 that I played with using a Dremel with a wand. Not saying you should, but I think it worked for me well enough.
Also thought I'd mention that along with your new springs, you really need to use either a spring cup, or a locator like the Comp Cams Spring Cups pn 4694-16 to keep the springs from dancing around and chewing up the heads. By the way, they fit around the guides great without any head mods, and seem to almost snap into the bottom of the beehive spring pn 26986-16. That aren't the ones you need for the solid roller mentioned earlier, but there better than stock Edel. springs IMO.
FWIW

Thanks for the pics and the info ssmonty it looks like the intake runner needs the most work.

theitalian 07-25-2012 07:28 PM

Your welcome fbird thank you for all the info you'v shared.

Block is at the machine shop hope to have it back next week ill post porting pics this weekend if i find time to work on the heads. Had to start with a new block the machinist bored the block a little tight last time and didn't want to do anything about it, so im using another shop for the machine work. I should be at 10:1 I did some monkey trading with a friend and he has a retro fit howards cam 232 int./236 exh at 50 0.510 int./0.533 exh lift i think i might use, it's new in the box. I'm a little over budget thats why im going to use that cam and i think it should do the trick??????..........

theitalian 08-09-2012 09:30 PM

So i decided to go with the howards cam my friend gave me a set of manley 22410-16 springs with it 1.250 , seat 130@1.750 open 334 at 1.200 he said the estreet retainers will work opinions? I should be home on the weekend I will post pics of the heads i got ported. Thanks
