f*ckin vw people Rolling Eyes

the ford vs chevy vs dodge vs imports goes on...now with heads. sadly, 1/2 the folks in this thread wouldn't know a quality part if it sat on their face and farted. not "targeting" anyone...but come the f*ck on...read this thread and look how some of you sound...

that said, I used jc whiney heads, sanded my lifters flat with 24 grit and did a break in with mobil 1 drained from my audi. revved it to the moon for 2.5 minutes put it in the shed, let mice piss all over it and pack the fins with grass and insulation. now what?

you guys kill me!

Are some of you saying that the Chinese 500 series heads I have are better than the new Mofoco 050 heads I bought from the classifieds? Shocked

I apologize. Those are not my intentions. I personally like the 050 heads a lot more.

This discussion about if the cooling passages ore open or not......I don't see it as big deal. If you want better cooling then there are lots of porting to be done on ALL the heads, even the stock ones.
The chinese are using the bare minimum amount of material in the casting and some like that because it saves them work, but if there are holes in your ports then don't come crying.

It is much easier to remove aluminum than to add it.

hi modok I had 3 different china heads with the guides coming lose from the head . now these are buggy guys and they can break any thing lol the head casting seems to be kind of soft alum. when I install the over size guides into the head modok have you run into this with china heads spencerfvee

I tried one set of Tims/china on my buddies engine. Hopefully he will drive it a lot so we can find out how they hold up.

My favorite heads are the ones made in mexico.

I have built several engines with the Tims AA castings. Granted, not many here drive their rides daily like I almost do, all run fine. I did notice that the AA 043 copy casting is a lot lighter than the original Mexican 043s. Tbh, i am biased with the head line they offer. Its a fair cost, quality ported head.
Id like to try a super pro one day, but i would likely step up to the ultra wedge 46mm heads if i ever did.
I haven't been able to compare the tims hwad built combos to anything of a similar combo. I built them for what the customer needed and wanted. If the Tims use the AA casting religiously and showed me face to face the differences in the diff castings, I believe them. They use their own in house 44 valve head in their own race car.
I'd like to try one of Roys 050s one day to so that I can give that head a fair assessment. I like the idea of a heavily finned casting like he does. Unfortunately made in the US detail doesn't move me as much as the price does. Call me un American it's ok. I did tours in the middle east armed, with indirect fire and constant insider threats daily.
Price VS quality VS time parts received is my bottom line.

Roy, your damned if you do. Damned if you dont. I'm on the side of wanting to see the numbers. Irregardless, advertising makes money. CB and DRD advertise flow numbers. I'm fairly confident that they sell lots of heads a year. It's advertising and it sells.

I am just finishing up the porting on the 043 china heads I got from Tims. First off I am not a fan of china stuff but at the same time I recognize that china parts vary greatly in design and quality by a very wide margin (some stuff is crap some is good).

What is nice about china stuff is they are willing to listen to experts and make it how the expert want's it but they have to listen to the right expert. So far I would NOT buy a china crank because IMO they listened to the wrong expert. Some one needed to hand them a berg crank and say make it like this.

These heads seem to act a lot like a VW head when porting as far how they cut, feel and look. The original guides have gone in the trash and I will use new quality ones and will get a feel for their fit. They manifold gasket suface is not bigger than stock but the added material around the port is enough to add a very nice big enough street port. I don't like the fact that there is no bump in the port for the valve spring (makes it hard to know where not to cut).

Tims admits he prefers the filled in 501 head for a weekend warrior engine because of the extra material.

Me, I want the 500/043 head because I will use as a daily driver and need all the cooling I can get. I want the ability to drive wherever and however I want.

I dont like the fact that it is a "fluff&buff" flow reading. where is the line drawn between "fluf&buff"& ported. the pockets were blended witch can make a big difference in flow, I blend my seats....from the chamber to the intake/exhaust flange . And just polishing does squat,but how much polishing?was any contours changed?at all???
I have roys 042's. they said they flow [email protected]" as I recall. that was out of the box.mine flowed 132 out of the box. out of the box is out of the box not "fluffy&buffy" unless all your unported heads receive the same treetment before being put in the box.
I think they should be re flo tested in the same manner that ded,cb,tim rev do.at the same lifts so they can be compared easyer.some people think because your flow listed is at .450" they have to have a cam that size.witch is way far from true.and that is not the max the head flows. those are nice flowing heads and with some proper work very good flowing. the same go's for the 042's.
with all this said.....I thought this thread was about the cooling and flow between the fins?? go figure Im stupid.sorry

I dont remove the guide boss just recontour them(tear drop win possiable) and only polish the ex side of chamber. if I had bought a set & flow tested out of the box , and they were not close... I would be pissed.
