W2 exhaust pattern to std LA flange headers

Kinda related to the W2 stroker discussion, just wanted people's opinions/thoughts on this. How much if any real world power does the standard flange cost on a staock size (which is kinda small) W2 dual bolt pattern head on say a 550 horse/550 lb/ft combo?

Does anyone have a picture of the two flanges or gaskets overlaying eachother?

I remember running my first set of W2's back in the early 80's...when they didn't have dual pattern castings and wishing (price and availability wise) they did.

if you don't get what you are looking for I can probably help you out tomorrow. You want to see a regular 1 7\8 header gasket on a W2 head right

That would be great, buddy, Thanks!!

I know the W2's as cast are more oval shape and a bit shorter but wider overall than a standard LA "dog leg" or "trapezoid" (on most aluminum castings) port

I'll see tomorrow if I have a set of standard
LA gasket.. I know I have a set of new W-2
gaskets.. are your W-2s untouched or ported..
if ported.. how much.. I know I have to open
up the gaskets on my W-2s to the inner bolt
holes

They are ported but I Intentionally left the port opening the standard small "as cast" size knowing headers may be an issue for the 66 A body.

thanks!

So what do you need

overlay of the LA gasket over std W2 port or gasket

I'll see what I can come up with tomorrow

Thanks buddy!

Worst case If I used LA headers I think I could massage the flanges and gaskets slightly to minimize the effects of the port mismatch.

Also I've seen a lot of high HP W2 motors running on dynos with standard LA ports and although we don't have any definative "back to back", the numbers the motors are producing are still pretty impressive.

not big horse power like most on here but i made 652 hp and 590 tq with LA TTI 1-7/8'' headers on my 440'' W2 motor.

Hey 79410AspenRT, can you PM me your combo?

Mine is only about a 575hp big torque moderate RPM street peice, not a full race motor. I'm probably just over thinking it, it's got plenty for a little 66 A body even if I just used Log manifolds, lol

Sorry Street.. I have NO LA stock type gaskets
just W-2s.. I tore my shop apart looking for
at least 1 of them.. nothing.. I was sure I
had a couple of stock stuff but NO

Hey buddy I got some bad knee issues going on and I can't even attempt to walk down to my shop. My Family Doctor gave me a shot of cortisone on Thursday to try to tame the pain down some till I see a specialist on Jan 8th. I was hoping to get some relief by now but so far nothing. Sorry about that but if I get some relief later I'll try my best.

No problem buddy, rest up and get better!

Sorry about that.. I had a roll of paper out and the W-2s
already traced out but couldnt find a LA exhaust gasket..
I swore I had some rebuild gaskets kit ones

i took a few pics but can't upload the pics on this site for you. PM me your email address and see if i can send them that way?

Hey Bobby, what's going on with the Val?
haven't herd anything in awhile.

Hey There, Mike

I wish I could say more but other than suspension (Tires/Wheels/F&R Sway bars/8.8 4 wheel discs and some frame mods there hasn't been a whole lot going on. I've had a lot of things going on so it's kinda been 'back burnered'.....My Cobra took almost 10 years so I'm about 3 1/2 into this one.....

I got this one picture....

I'm out of time right now, but I'll take a few full photos later on tonight.

Glad you had asked this question, I am contemplating running my Hooker headers for an extra season given that the TTI pipes purchase is a pretty darn steep wall to climb, and well, the budget has been nearly exhausted by the stroker build already...LOL!

Sorry it took me a bit longer, but OK, here they are.

So a bit of a story first...I've been using these MrGasket pieces for some time now, as I needed to match up my Hooker headers to the stock '596 castings I ended up picking up the #5935 & #5949 gaskets. The pics show the differences between these. I think the 5949 fit better, just a shorter port and seems to be raised in the right spot on the center exhaust ports.

1) #5935


2) #5949


3) #5935 center ports


4) #5949 center ports


5) gasket overlap

Thanks everyone for the really good information!!

Those 5949's dont look to bad.

Yup I originally posted them here:

In the last picture you can see I actually used the standard exhaust gasket as a templet to paint it's pattern over a W2 adpater flange this is the truest comparison

The last shot was to show how much the 1-7/8th header tubes extend over the econo head inner exhaust bolt patteren

Thanks!!
