I was wondering if the slp tri-y headers will fit 84 Z28 305 L69 with L98 alluminum angle plug heads.SLP says their present models DO NOT fit these heads.I have called 1 time and e-mailed 2 times to make sure but have not asked about tri-ys .If any one can help it would be greatly appreciated......Thanx......... 65 panhed.

 

I am running the SLP 1 3/4 coated, non AIR headers on my 350 with the Aluminum L98 heads. its a little tough to get at the plugs but they will work.

 

It will fit just fine. I originally ran a 350 with L98 Alum angle plug heads with SLP Tri-Y headers with no problem at all. Its a nice setup. You will need a shortened spark plug socket to get to some of the plugs but its not bad at all.

 

I heard the SLP headers dont match the D heads

 

Yes there are a lot of concerns with these headers but they are really supposed to run well and they will keep me smog legal.....

 

The 1 3/4" line up just fine, but the 1 5/8" (like all 1 5/8" headers from all manufacturers) are questionable.

 

Hmmm no more posts.......any headers to fit L98s? It looks like SLP 1a3/4 and see what happens......

 

you must be new lol.
Hooker 2055's.

 

yeah thats obvious Imanewguy but hooker says no way on the 2055s dude........he called me dude,......dude......thanx........I will try to be less obvious from now on

 

sratches head......oooooook
If I gave misinformation, sorry I'll try to only answer more, more obvious q's.

 

yeah I really wanted to use a good proven header in the smog legal shorty style without spending a thousand bucks.I asked about grinding the header ports but that wouldn't work either.I guess that I will call hooker again, their gonna know me on a 1st name basis when I'm through............thanx for input

 

Thats strange . I have hooker 2055s and aluminum L98 heads . I measured the port on the heads and the ones on the headers and the ports on the headers are bigger than the ports on the heads length and width wize .

 

well I guess I'm gonna go with tri yz and see what happens..Thanx to all for the input and I will keep everyone up to date on this project. From stock L69 to ZZ4 heads with 55cc chambers comp cams XE262 or XE268 weiand action plus 8000 with holley 650 spreadbore 6210 and msd 6AL box with msd billet distributor and coil...........Please join me in a silent prayer........
