Button head for cox conquest.

Post  JPvelo on Sat Jul 08, 2017 4:51 pm

I have recently acquired 2 conquest .15's and a bag of button type glow heads marked conquest/Rossi .15.  
The conquest engines I have use standard glow plugs. Is there a big performance increase in switching to the button type head?

Thanks,
Jim

If you are talking about a nelson type of plug / head I sleeved a nelson head button to fit a Conquest and picked up 800 -1000 rpm. Going to the C*x type head with insert and clamp head is worth 400 - 500 rpm over the std plug head.
