Thread: 302 cyl head print (needed!)

Tweet

I need a cyl head print for a 302. my casting number is a d08e head, but any 302 head will basicly work. I mainly just need the exhaust face.
Thanks,
Dave Henderlong

just what in the he double hockey sticks are you asking for ....ted

First, what is a "Cyl head print" of the "...exhaust face" on a SBF 302? Second, what specifically are you trying to do, and it's likely someone here can answer your question.

any small block ford exhaust gasket will give you the pattern layout if that`s what you mean ( 289 /302 /351 windsor ..

302. its a small block ford engine. commonly known as the old 5.0l. My cylinder head casting numbers are d08e. Those are my heads for my 302ci.
I need an exhaust port face print, meaning the exact dimentions of an exhaust manifold flange that will fit on the 302ci.
Im trying to find the print of the head so i can make an exhaust flange that will mount up to my d08e cylinder head.
I'v been trying to trace the gasket on a piece of paper, but i need more acuate dimentions.
So if you have any information on the blueprints, please post it.

I think most everyone here understands that a 302 and 5.0L are the same engine, and I don't have engineering drawings of the SBF 302/5.0L heads, but I chased header flanges through a lot of sources and ended up buying a pair from Stainless Headers Manufacturing, Inc out of MN - 3/8" thick and precise fit stock ports for $74 delivered ($29.95 each and $13 shipping March 2010) http://www.stainlessheaders.com/flanges He has flanges for all heads, either stainless or mild steel, and he knows his business. Headers by Ed is another place that really knows their heads - http://www.headersbyed.com/ Both Summit & Jegs also have flanges, bare or stubs, with prices ranging from <$50 to $150. Hard to believe you can make a set cheaper than you can buy them today, but I may not understand what you're doing.

You can go to the site of Schoenfeld headers and download about any header flange spec you might want and/or buy a gasket to copy from several aftermarket heads/bolt patterns

thanks Louey, I had some of the prints around here but no way to upload them so just mentioned that Schoenfeld had them. I usually get the gaskets and mild steel flanges from them , modify the flanges to fit our heads and send the prints and gaskets/flanges to Stainless Headers in MN to have the flanges made from Stainless Steel .

I agree with the guys. Unless you have the equipment to cut those flanges yourself buy ones from one of the vendors who have them on the shelf. 289-302-351 header flanges are a dime a dozen, no magic whatsoever, so why reinvent the wheel?

THANK YOU Louey!. you have no idea how long i have been trying to find these.BUT....

i still need a location for the mounting stud holes (to hold the flange to the head). These are not givin. and they look off centerd from the port holes. How do i find this?
I have the right tools to cut these out. I can make them cheaper that 75 bucks or whatever
Depending on the price of steel i can basicly make the flange for around 5 cents a pound.

This flange will then be tig welded to a set of custom flared pipes. I'l try to keep you guys updated.

And by reinventing the wheel, if it is not perfect there is stll room for inprovment

2.00/2.38?????are the bolt spacings and they are in a straight line!!!

if these don't supply you with the info you need you can go to their site and download more---or buy a gasket!!!!!

We seem to have a basic mis-communication here, or at least I am very confused. This flange is a part of the header, and it bolts to the machined head surface with the eight header bolts adjacent to each exhaust port, into the 3/8x16 threaded holes in the head. Your "custom flared pipes" weld directly into the oblong holes in the header flange, unless you buy flanges that already have stubouts - then your primary pipes weld to the stubs instead.

The only thing I could see that might be different is if you have a set of the SVO oval port heads, which have the bolt holes at an angle because there's not enough meat at the sides. If you have those heads then your header flanges are drilled in that pattern vs the straight line shown in the drawing Louey posted. Picture of the SVO is attached. Is this what you have??

Dang - all you needed was a piece of poster paper from Wally World (35 cents) and a ball pein hammer that has a good rounded head - and made the same way you make that water outlet or differential gasket at 9:00 PM on a Saturday night. Those Ford exhaust gaskets - none, regardless of brand are a very good fit except those expensive Earl's - or so I found out when I used the GT40 heads on the '31

Amen, brother!! And as I have learned, some of the aftermarket aluminum heads take some liberties with their castings, making sealing things up a bit of a challenge sometimes. If you're going to spend valuable time making flanges from scratch I would make them to exactly match the heads you are holding, not to match somebody's dimension drawing. At the very least you need to verify every dimension against your heads, IMO.
