240Z Header Recommendation

[jmark]

I picked up a vintage copy of "How to Modify 510, 610, 240Z Engines & Chassis" printed 1973. In it Jere Stahl discusses the merit of using a 1 3/8" primary header on a stock motor 240Z. Great book if you can get a copy.

This is the book I am talking about.

Any new word on Clifford tooling up to produce some more Z headers. I just installed a Pacesetter via Jet-Hot, but would replace it right away if I could get a Clifford!!!

Not that I have heard Russell. =Enigma= bought a nice one off Ebay.

Well I got the header and it's in pretty good shape, however the flange seems to be fairly warped. This might be by design and I'd love someone to comment, but I won't know until I go to mount it. This won't happen for a while. If I find that I need to have the flange planed or ground level, it shouldn't be too big a deal since it's so damn thick. The header will eventually make it way onto a 280ZX motor I grabbed a while back for a swap.

I tracked down the seller (Peter somthing) to the zcar.com forum where he posted some info that I wish I had before bidding, but all in all I'm satisfied at this point. We'll see what happens when I go to mount it.....

Here's a link to the info he posted on zcar.com:

According to Peter:

I just layed the straight edge over the flange area. If you were looking at it in the car, it's convex at 3 & 4 then 1 & 6 pull away about 3/16". And there is a slight twist.

=Enigma= The best thing you could do at this point is buy a new gasket. Who knows how old and deformed the one that came with the header is. Then you will be able to port match the header to the head. First use a feeler gauge to find out how far out of flat it is by mounting it to the head without a gasket. After the flange is milled the apropriate amount, port match the head to the gasket and the header to the gasket as well. I don't know if you are using inserts or not. Have you bolted it to your head yet? If there is a twist that prevents it from being bolted on properly, that will have to be addressed first. It's a shame this wasn't done before it was coated. you will just have to be more careful with it. After all is said and done, you will still have gotten a great header for the money. Good Luck, and let us know how you make out with it.

Just a heads up, you'll soon be able to order Stahl headers for your Z from MSA.

Sal was at our Z club meeting last Tuesday night; he announced that; yes, MSA will sell Stahl headers but they will not be cheap. I think the price was up around $900. He also mentioned that the MSA header has been improved.

Ron, Those are old prices. If you read the note on the website it mentions this. I think the new price is $862.

If you're going to lay down $900 for a header you might as well do a before and after dyno run to show us all what the difference is.

Hopefully Nissan Sport is going to test a bunch of headers for a future issue. I believe they are going to use Art's Z.
