Anybody have any tips for installing a Riley 2 Port

My father is putting a Riley 2 Port on a stock Model A motor and I was wondering if anybody has experience with doing this in the past. I know they are pretty straight forward but we don't want to overlook anything simple that will make us have to back track. We also have a couple old aftermarket ground cams so I'm assuming we should replace the stock one? Thanks.

 

Charlie Yapp had a booklet that he gave away that outlined installing a Riley Two Port. You might contact him through Secrets of Speed.

REAL or a reproduction? I've read that there are problems with the reproduction 2Ports. Send me a PM with your address and I'll send you a Xerox of this Xerox. Bob

 

Hey Bob it's a repro......where do the problems lay?

 

Curious on how the 2 port Riley installment came ????? cam, intake,
any addition changes !!!! thanks

 

We ended up running out of time so we used a Super Winfield head, new higher lift cam and a Evans 2 carb intake, the motor runs great so we are going to build a new motor with the 2 port so we are basically starting over.
