Hey people, I haven't posted here in awhile but thought I'd drop in with a question.

I'm about to do a head swap on my ZZ4 and would like to know if anyone knows the difference between "Angle Plug" and "L98 Style Angle Plug" heads.

I currently have the L98 aluminum heads (stock) on my ZZ4, and plan on going with the AFR 195's. They come in straight, angle, and L98 angle.

Has anyone ever actually SEEN the difference in the L98 angle and the standard angle plug heads?

I'm using the Hooker Super Comp Headers right now, and it's a pain with the L98 angle plugs, and I figured if the standard angle plugs were more accessable, I'd go that route.

Thanks in advance for your help,

Steve

If you're not having any clearance problems now, I wouldn't change anything. I'd be getting me a set of the "L98 angled"...if it ain't broke, don't fix it.

Center bolt vs. perimeter bolt valve covers perhaps?

What RB said, and the different angle for the TPI intake manifold.

 

They're center bolt valve covers. I no longer have the TPI base. The intake is the standard old style bolt hole base (Miniram).
