There are a few different options for the 65cc AFR 195 Heads and spark plug holes. It looks like there is a 1034 (straight), 1040 (angle), and 1041 (angle). I found another thread regarding Dyno Don Headers and spark plug angles, it looked like there was some confusion as to whether straight plugs worked better than angle plugs on that thread, then there was talk of L98 angle plugs. AFR from what I can see on the website only comes with straight or angle plugs. Just wondering if anybody knows the correct AFR head part # that would go with Dyno Don headers?
Thanks

 

They work with all heads but best with angle plugs.

 

Thanks Don...just ordered the 1040s with angle plug.

 

If you are running 1040's, with Don's headers, you will absolutely need a stubby spark plug socket. Plug changes are easy, there's just no room for a regular sockets.

Also, get Remflex 2017 header gaskets. Many of the other gaskets recommended cover up part of the afr ports. The remflex's match the header and the cylinder port perfectly.

 

I ran into this issue on my last car. I coudnt find AFR heads in L98 angle....which at the time was the style to use with the SLP headers I was running. Im running stock heads on my current car now.
I'm running the metal 4th gen LT1 spark plug boot protectors on my car with DD headers. No issues at all. They help keep heat away from the boots.
