I have a JFUD4 type distributor that was running an E12 head with low compression piano top pistons. The Distributor has a Vacuum advance. I will be running the 9.5 comp pistons, Does anyone know anything about this distributor and whether i can use it with my new pistons? or should i go for the Tii mechanical advance distributor.
I would also like to know if you can use unleaded petrol with the E12 head, or do you need to change the vavle seats or anything else.
Thanks for any help
