shorty headers
Anybody know of any block hugger shorty headers to fit an 85 vette.I saw some patriot shortys in Jegs catalogue that look like they might fit.Has anybody used these or similar ones?

Can't help you with an answer, but if it were me, I wouldn't do it. They won't give you any additional power or do anything beneficial for your car. They will however, lighten your wallet. If you want to do the header thing, go longtubes or nothing.

With all due respect I call 
on this statement. It all depends on total budget that the individual has to put into the system. There are definite gains from shorty headers, maybe less on some cars than others, depending on factory exhaust manifold design. You can still gain 5-10hp from a shorty header and not run into the expense of aftermarket cats, exhaust system mods etc. Shorty's are a single expense because they bolt in and are emissions friendly. LT require additional mods and may not be emissions friendly.
I know CF promotes LT headers or bust, however they are not the end all for mods.
As "Vis" always says "show me the dyno numbers"
OP wanted part nos. or manufacturers of direct fit shorty headers, not a lesson on what he should choose in lieu of his objective.
Ok lets start this debate again!

The exhaust manifolds on the 85 are not cast iron, but thin wall tube just like headers. They are restricted where they gather and dump into the exhaust pipe (front "Y") on the 85. You should see little or no weight savings.

The reason I am asking is because I have angle plugs on my car .In order to get even shorty plugs to fit I had to dimple the already small tubes to make them fit .Also I have World Products heads and the exhaust ports are bigger than the stock manifolds,I also remember an article in Chevy High performance comparing headers and they were surprised at the power gains made by some of the shorty headers.So I know some can flow o.k. Just wondering if anyone out thier has found a pair that works .Thanks Steve

I have World Products sportsman ll heads with angled plugs. I order to get the spark plugs to fit I had to dimple the heck on the tubes to get even accel shorty plugs to fit.I ported the stock headers as much as possible to match the exhaust ports on the heads, but they still are to small.

Shorty's
I agree with BigGrizzy.. yes there may be small gains with shorties, if any.. But everyone requirements and goals are different!
From some.. just the looks and min gains are enough.. other need a 800+ hp monster.. some want as much as they can get with being Smog Compliant. Some have an endless wallet other are saving for month to by a single upgrade.
So... lets all just help Steve get what he wants.. if and when he asks for information or an opinon.. we will give it to him then..
I know Hooker 2149HKR states that This header comes with accommodations for EGR, oxygen sensor, and air pump (smog tree welded to header). These are mid length and coated.
But your not using the smog.. 2149HKR or 2151HKR.
Suggest you check with some of the sponser or the Jegs/summit catalogs for other brands..

If emissions aren't a concern, the LTx shorty headers should work for you and are easier to find than for the L98`. The head flange and collector are in the same location as on the L98 although the collector is ever so slightly larger on the LTx. The air tubes/egr riser are different on the LTx also but probably could be adapted without too much effort.
SLP used to make a nice stainless shorty. The hooker shorty is 2061HKR.

Someone who owns an '89 said they measured the openings on their stock headers @ 1 1/4"... plus they have the air tube causing turbulence.
Most LT installers use 1 5/8" or 1 3/4" headers. Why wouldn't an upgrade in shorties be good too? (Excluding the improved scavenging affect of LT Headers).
