i have looked my area over and cant find another one.. i am sure there is one to be had i want one for parts. This can be annoying!

You can use parts from any 2.8/3.1 5-speed (Getrag 282) equipped W-body. What exactly are you looking for?

honestly i need a set of heads. I was hoping i could use the heads i got but i guess i need a newer intake. The heads i got came off a 1995 Lumina 10154743 casting.

 

The guy i got them from said they should work fine... from what i am hearing he is wrong.

A 1995 Lumina has a 3100 engine, and I don't think the heads are compatible. You'd need heads from a 3.1 MPFI engine. Anything from a Cutlass Supreme, earlier Lumina, Grand Prix, or Regal 3.1 should work. Hell, you could get them off a Cavalier with a 3.1 engine...

You don't need 5-speed parts for your engine. Theres shitloads of 2.8/3.1 parts at any junkyard.

If you have the 3100 heads, why not put 3100 intakes on as well? Since you're stripping to the block. The 3100 top end will give you a bit more pep.

Ditto. You'll need the lower intake, plenum, tb, vacuum lines, coolant pipe, exhaust manifolds, and a few other misc. things, but it will give a good boost in power and gas mileage, and you already have the heads so why not...

i dread the day when you can't find a good set of heads for the 3.1

Not be able to find a set of heads for a 3X00... heh, that will be the day of the apocolypse. The 2.8/3.1/3100/3400 have been used in so many different cars, they cant be hard to find.
