OHHHHH YEAH that's the middle school i went to yepp im a schmuck.
This is the high school i go to know(senior hells yeah!) uhhh yeah this is only about half the length of it... as you can see we descriminate against the handicapped. No im just kidding it was taken across the street in a different parking lot. My schools almost two blocks long and about one block wide and has two levels.


I definitely want flames though

MMMM that proabably means my header is lining up perfectly to to my stock head

 

Think removing this amount will help? No kiddin...:impatient




Holly Cow...talk about blockage

 

Did you get a matched exhaust flange gasket with the Webb head?
If so then why not make a template from it or use it to lay over the new header flange to mark it up for porting.

 

BahamaBart, your OBX is perfect with the stock head ports, nice little anti-reversion step in there.

 

This is consistent with what we saw..... take out that material and good things will happen

 

Looks like there won't be much gasket after you cut - #1. If a leak starts, it will get bad quick.

 

Which header is that again?

 

The Megan that's not made by Megan???

 

The photo of the header flange material to remove is what I saw when I put mine on--I just used a die grinder to remove all that red stuff down to the primaries.

cheers,

 

The problem is, there won't be much interference for the flange gasket. If that was my header, I'de be welding another 1/8"+ to the #1 corner before making the cut. There is a, relatively important, relibality issue after the cut on #1.

 

which is what "we" (Dave...I sat and watched) did.....it is interesting to note that there is still a lip that would probably benefit from adding some material to make it smooth but we did not do that

 

Excuse a neophyte question here, but what's the easiest way to determine exactly how much/what needs to be milled? If putting a new header on you don't have deposits conveniently marking the way. tia

 

The best way that I have found is to make a template out of thin copper or aluminum ( 20g is what I use ). I prefer copper as it can be a little easier to use. Save the template for that head so it may be used on another header or if you are fabing your own header.

 

Here ya go...one down...three to go...

 

Looking Good!

 

REALLY? you checked it out? anti-reversion?

My previous post was just a leg hump for MISFITOY .

 

After you get done grinding them headers you'll definetely have to let us know the results. I am tempted now to pull my header off. Just for a look.

 

Didn't you see those pictures on the OBX thread some time ago. I posted pictures of before and after using the OEM flange gasket on my OBX. The OEM gasket is larger than the OEM head ports I just made them match perfectly.
Thing is all this stuff has been discussed before on here and now being rediscovered.
Always check and recheck it’s the details that count.

 

You are right, but it did not seem relevant to me at the time ( I was wrong)

so many threads......... so little time

 

I'm curious as well - I'm not sure I want to KNOW!

 

He is making the ports larger to match up with his ported/polished cylinder head.

 

Like Spidy said - so many posts so little time. If you know the thread tell me and I will go back and take a look. I used the OBX gasket that came with the header.

 

Bye Bye bulls eyes...Pristine glass by Pilkington, installed Friday by Henderson Glass...made in Findland...Findland? I thought they only produce hot leggy blonds... They make very nice glass too...The thought of Hot Leggy Blonds making Mini glass makes me warm all over

Tint band thanks to my good friend 4GASM... I used a laser leveler to produce a clean water line...

 

Hotness! And I see you put your wipers back on haha
