I have a 96 Caprice wagon. The engine is the iron head. If I want to strap on aluminum angle plug heads....will I have any interferance problems? Will the plugs hit the exhaust manifolds or any other fit problems? Hope to get answer soon. Thanks!

the heads will fit.

if the heads aren't ported you will not see any gain.

What other mods have you done to the car?

THANKS for the rapid reply!
No mods yet....just starting. I AM having the head/cam package done and many other mods. Just starting the build.

What I'm asking is whether the plugs will hit the manifolds since they are at an angle in these heads (the iron heads are straight plugs IIRC). Or hit anything else on a wagon configuration? AND...will it create a problem installing headers in the wagon with plug clearance or pipe line up?

If you're swapping the heads, why would you put exhaust manifolds back on?

I'm running the Afterburner headers with LT4 angle plug heads with no issues.

Yeah......

Heads/cam and "many other mods".......I'm really hoping that this is a problem of terminology and that you're really not gonna put stock manifolds on a built engine.

In my opinion, you really want headers on your modified B-body......and the Gen-1 or Gen-2 Tri-Y's from Clear Image Automotive would likely be best for your set-up.......

Well....give me some credit. I'm getting older but not dumber...LOL:D I did ask about headers and there are 2 cars involved that I didn't want to get into here. Just wanted the info. NO...my wagon will not have stock manifolds. :)
Yeah....I've heard Tri-Y's were the operative choice. Does that include wagons?
And THANKS for the info, guys.

Gen 1 tri-y's from CIA will cause a clearance issue with aluminum LT1 heads because of the angled plug, you'll need Gen 2.

assuming you're talking about stock LT1 aluminum heads (camaro,TA etc)

I was told this by Dan, the owner of CIA who makes the headers, i have no first hand experience.

when i bought my headers from him for my wagon a month or so ago he asked me if i was ever gonna go with Aluminum heads and i said no.

He said: Good, because the angled plugs on aluminum heads creat a clearance issue with Gen 1 tri-y's

he asked because i was contemplating gen 1's or Gen 2's and other than looks i asked for differences.

what's your experience with this? now i'm interested because if the guy who makes the headers is wrong and there is no issue with clearance that opens up my options for going with aluminum ported heads in the next year or so.

Dan has to deal with some customers who have ten thumbs and half a clue. A clearance issue is for them is just a tight spot for two-thumbed types. I've got Gen I Tri-Ys on 95 Camaro heads. A couple of the spark plugs are a bit tricky to change, but not a huge deal. If the Gen IIs have better clearance, I say go for it. I'm just sayin' the Gen I version is doable.
