what valve overlap do you suggest?

will it run on 91 pump gas?

thanks,

The 20/21 is made by Web cams not me.
The DC20 is a little bigger compared to the web 20/21, the closest grind I have is the DC19. I would not recommend either with 11.5-1 compression and 91 octane.
Even if you went with twin plugs the tune up window would be narrow.
Something a little bigger like the Dc24 would work well (with twin plugs).
