My friend has a set of heads: "190cc Street Heads, Angle Plug, 68cc" On the website the only difference in the description is "L98 Angle Plug" which are the heads I might need; instead of just Angle Plug. So my question is Will these heads work or can I modify those to fit? Thanks

Yeah, they'll work fine. Depending on engine stats, they MIGHT be too big, but the AFRs don't suffer from that like others. I have some 195s on my L-98,and they work just fine.

 

The angle plugs are the L98 and they recommended the L98 angle plugs first off for stock L98 engines but if not a L98 if you are thinking of running SLP or Hooker headers because they give you easier access to the plugs

 

So if you ran SLP Headers then get straight plug AFRS???

Honda engines ROCK, I have one on my lawn mower but I still have to push it.

 

I think the L98 angle plugs are for the Corvettes, just get the 64cc chamber straight plug heads.
