exhaust
Hey guys...I am attempting to install a set of flow tech headers on a 1979 Camaro Z28. I am a novis! Haven't worked on a car since the 60's. These headers (Holley) suggest "shorty plugs"? I had never heard of these plugs and most auto parts stores don't store them. Holley says to use std plugs and I should be OK with 1/4" space between header and plug? Am I looking for a problem. Also they are awful close to the auto trans lines! Did I make a really dumb mistake with this purchase? You get what you pay for? Any suggestions? Do you install plugs and wires before final install?

I haven't installed that set of headers but would guess that the short plugs provide better clearance for some reason. Check Summit for the plugs. Headers always distribute more heat in the engine bay and clearancing is usually a problem. You can wrap the headers with heat wrap (also from summit) which will lower the heat. I also use heat shield boots on my plug wires close to the headers to keep from frying the wires. You can also make a bright metal shield around things that are particularly sensative to heat. Starters are commonly shielded.

my muffler shop hates flow tech headers because of bad quality control: he says many sets have leaks where they are welded inside the collectors.
But... I just talked to a pontiac racing engine guy in canada who recommended Flow Tech headers just now. said even in Hookers he's seen bad welds in the collectors. oh well.. [ August 08, 2002: Message edited by: bullheimer ]</p>

Accel makes a header plug. Part number is 8199. This is a U-groove plug, but I'm sure they have regular ones as well.

well since a street avenger is a Holley, i say go with Holley. actually you can find a used one for like $10!! just rebuild it for $25! i love them. believe it or not there are people out there who hate holleys' guts!!! they give them away. one friend gave me 4 or 5 for $20!! (he loves carters) if i was buying brand new i think i'd try a road Demon baby!!!
