ive searched the internet looking for some aftermarket heads that fit the 91 L98. It doesnt say anywhere in the description of them what years they fit.

some links would be great.

thanks

 

you could always try to find some aluminum 'vette heads! that's what i'm trying to do! or some vortec's!

 

Any heads that have the 87 up bolt pattern and egr passages will work on your L98.

 

i have no egr. i am runnin a lt1 converted intake with the l98 bolt pattern.

i cant find a description of what year the aftermarket heads fit so i can find the right bolt pattern.

Dart iron eagles ETC. doesnt say what bolt pattern they have.......


links please

 

trick flow heads will fit and work great with LT1 intake. it has the egr passages and fits 87 up. believe they have angledplugs to fit l98 as well
try summit racing for these heads

AFR has probly the best heads with EGR passages and without for L98's and the angled plugs too.

Slot the center bolt holes on the intake and you can use any traditional SBC head, 87 and up used different bolt angles for the center bolt holes (I supposed that you can use an ’85 or 86 manifold base if you want to use older heads also)

Later vortec heads require a vortec manifold base.

Angle plug heads tend to be a headache with most headers

 

There are many heads for your car, I cant beleive that you cant find any,,, AFR,,, Trick Flow,,, Edelbrock,,, Patriot Performance.

Go to Summit Racing's site and check out multiple heads for you.
