Picture of combustion chamber < untouched
exhaust porting, you can see the tool marks.
intake ports < untouched
I have more pictures but need to resize to post here if anyone is interested.

 

What does it all mean? Good or bad?

Are you changing heads?

 

u know this l00ks a bit like a head job i did on a BUG motor.. ..so if its jus a ported head and not polish then its a fair job but all that toolin' will cause it to flow poorly but its a fair job

very weird that the intake ports were left untouched though???
are the valves 3-angled?

 

" What does it all mean? Good or bad?" IMO not the best.

"Are you changing heads?" Not at the present time or this product.

 

.......... yikes,

Better hold my tongue on this

 

"That looks kinda....not good" - Invader Zim

WOW. My Cossie looked like jewelry compared to that!

 

no, it's more like CRAP!

 

no need to edit, don't worry I agree with ya.

The webb head is alot better right?

 

not so zoomed pics of the webb head, you can tell from them though that it is better. Almost 17 more hp, brian told me.

 

Pilo head:

 

Which is better, pilo or Webb?

 

I'm sure they tested them in Antarctica though, heaven forbid I wouldn't want to come out to my car one morning in -80* and not have it start!

I have a JCW why am I bashing it?

Which ever flows more air...

 

Webb has one version with the schrick street cam, hand ported and has bigger intake and exhuast valves. For $1805.

The Pilo has a zillion options but to have a fully decked out one will be $3170!

 

is this ur head ur showin' pics on???

 

Protek auto aka Med engineering in UK has about the best head on the market. Last year at this time cheaper than Webb and Pilo. Med has some great options with matching ports to headers and doing the intake to match ports to head for better flow.. Since the dollar has tumbled they may be more expensive. Don't forget about Endyn. very nice work also.

 

That is some incredibly crappy head work on the JCW!

 

 

I don't think this should even be considered a performance option. I'm looking at a stock head and the ports look better than that peice of crap. I wouldn't be suprised if their "porting" hurt the performance of the head.

JCW head = BARF!

 

Close.
JCW head = Crap!
And spendy crap at that!

 

JCW intake port < untouched
Combustion chambers < untouched

 

No way................... I would never buy anything that looked like that much less consider installing it on my MCS.
I can do better than that for just a clean up but don't have the facilities to flow test.


Endyns head work is art in metal.

 

The Webb head flows 178 CFM exhaust and 220 CFM intake at .450 lift according to the flow chart I saw.

Here is a link with more head info:

i did a port job on a head, (practice) & it looked like that u would think that JCW stuff would be better but it does not surprise me its all junk
theres a thread on here for this "JCW" junk/crap

 

hmmm...JCW taps the head with a die-grinder, and dealers charge 10 hours labor to install it...I guess that's the infamous refined JCW bits for ya....
