Sunbeam Specialties sells a stainless steel unit that is a copy of the optional competition header that was available from Rootes. The tubes are equal length unlike the standard series 1 and 2.

mototron,
do you notice any difference between the pipes on the left and the ones on the right? the ones on the left are a set of very old unused original series 1 and 2 pipes. the ones on the right are what rick sells and also the same as the originals on two of my harringtons. why were they used on the LeMans instead of the standard units?

Neither of those headers are equal length, they are what are called tri-y headers.

Equal length headers would have a single collector where all 4 tubes become 1 (instead of 2 into 1, 2 into 1, 2 into 1).

thanks for your explanation. the stainless ones on the right are not the same as the originals but they are what rick sells. I would say they're made by falcon.

Default still looking...

So it sounds like aftermarket 4 into 1 headers are NOT readily available?

I'm going to see a header guy this Thursday about Tiger headers and I plan to talk Alpine headers as well.

SO, HERE IS a CALL for everyone interested in a set of headers, speak up!

Let me / us know what you are interested in.

I'm thinking top shelf would be Stainless steel with a merged collector.

But mild steel with a lower cost collector may be a starting point.

Tube sizes are a bit up in the air at this point, but the plan is to make the fixtures with different tubes sizes in mind.

I'll know more by the end of the month, but don't hesitate to throw your comment in.

Thanks.

First, the difference between those two versions is simply that one is set up to make room for the larger alternator!

Second, let me know for the headers. I might be interested. But they ID would have to be large enough for the Holbay head.

I'd probably rather have steel and get them jet coated than stainless.

Jay,
The style you say were made to clear the alternator were used prior to Alpines having an alternator. They were on all of my LeMans. I do have the originals even though one Harrington now has the stainless steel and the current project will use the stainless. My other early Alpines all had the other one. My later series 4 and 5 Alpines had cast iron exhaust manifolds. The series 5 has the alternator. I have had too many problems with JetHot coatings. The 69 exhaust manifold has been recoated but continues to rust. Looks good for a couple years but doesn't last.

FWIW, I had mine coated by a local shop 20 years ago - in the chrome color. Still in great shape. Sadly, they are not in business anymore (Gold Coast Coatings, Oxnard, CA).

Also, I have had continuous problems with blown exhaust gaskets. If anyone went to the trouble to do this, I certainly would prefer that rather than four flanges, to have one long/thick piece that is cut out for the pipes to be attached to.
