TooWoomba plant New Zealand?

Anyone know how these heads actually perform on a 350? I've seen the flow#s, but I don't feel that #s always accurately predict performance.

In flows about 245 @ .500 lift
Ex seems a bit slack at about 148 @ .500 lift.

28 inches water.

They say 10 or 15% better than standard 906..
They have 906 cast# also.

The 350 would be 10.35/1, tight quench 2vr flats, Crane hyd roller is max for stock converter and computer which runs out at 6200... can't remember the grind#
They're back on Ebay again for 99 bucks each. <the heads CH350E

Toowoomba is the company that did the Protopline head casting, they know what they are doing. I haven't used one of their EngineQuest castings but have looked one over pretty good, casting quality looks as good as the ProTopline stuff was. I do see these as pretty highly reguarded around the web by engine builders who do a lot of IMCA Modified work.

I'm going to have to look at that $99 ad

Doesn't get much better than Protopline.

I saw my first pr. of EQ heads last spring. They were the large intake runner models.

The casting was flawless with great looking machine work. The seats and guides were perfect..

Customer says they flow way more than his 406 can use..

[GMC boogie]

Thats a great price,almost too good.

I would guess these heads do not have the raised intake ports like Vortecs since they have the pre 86 intake face.

I have their 200cc performance heads (not vortec) on my 406. My engine builder had nothing but great things to say about the heads when he set them up and he had never even heard of eq. Never had my motor dynoed or ran at the track but it will definately eat with a th350 and 373 gear. Guys freak when I tell them how little I have in my heads. Based on some cars I've played with and knowing what they run @ the track I'm real happy them. They have an aluminum head out now that's pretty cheap also. I've noticed they're aren't offering the heads in the 190-220cc range anymore. Not sure what's up with that.

The item #CH350C were used on this build. It produced 445 lb-ft of torque at 4,400 rpm, and 447 hp occurring at a peak power rpm of 6,200 on a vortec short block 350 with 10:1 CR, 750 carb, air gap style intake (professional products), Comp Cam custom grind 224 @ .050 on both sides on a 108 lsa, 1.6 roller rockers, 1 3/4" full length headers, summit hei distributor with a Dyna-Module...

Wow 50$ shipping isnt bad at all.

They have the raised runners like a Vortec head but an old style intake bolt pattern.

What concerns me is finding an old style pre '86 intake that matches the ports.

Maybe they are out there,have not really looked.

Yep,^^^ Usually have to run a Victor style Intake to have enough meat to match the ports.

They they carry the RHS name now. Same heads from what I can determine. they even claim to have tweaked up a bit. What EQ heads that remain are the end of the line for the EQ label, and they are out of some of the popular numbers.
I have a Crane cam (also out of business) that I want to match up to these heads. It is a hyd roller 2032 .. grind# 104224 ...214/220@.050" adv 270/276 lobe separation 112.
Wonder how it will do with a 350 with .041" Quench 2vr flat same intake and the same heads, basically same build that VW Super referenced on the link he posted? This cam is a step down, maybe two.. I haven't tried to load the cam specs in my dyno sim.

So......what intake would you run with these heads? Would you have to run a victor intake? Is there any lower rpm range intake that will fit these heads?

[macx]

EQ head info & source, also flow #'s

http://www.rogersperformance.com/EQ.htm
http://www.rogersperformance.com/EQFlow.htm

That PHR build article made it sound like the 180 runner heads
are also basically Vortecs.

It doesn't really say on the Roger's site, so I emailed and asked.

He said on their listing that only the ones described as Vortecs
are Vortec style comb chambers & ports.

He said the other ones are basically a D shaped comb chamber.

I'm going to try this dual plane on my next go because I'm using a medium solid roller>>

Although there are several lower priced/lower RPM dual planes listed on ebay that compliment a smaller RV cam, and was very well matched to the last one I did using a Melling MTC1, that tops out at about 5200, all in all a great street cam.

I'm off of any intake which is not made for vortec raised ports; lucky to have any upper lip left at all. I port match any intake I install and the one from the link was recommended by Skip White, so thought I'd give it a try..
