Paul,
Jerry Hey is your man on the PP rotor housings - the original 13B ports are filled with high temp epoxy to seal them off and fill the cavity. Someone somewhere said the cavity really didn't need filling - I'm personally unsure!

Subject: [FlyRotary] peripheral ports

Hi, all....I need to make an inquiry regarding peripheral ports.  I understand that the housings get the round peripheral ports installed, and that the exhaust port is also modified to complete the P-Port modification to the rotor housings.
     What, if anything needs to be done to the existing center and end plates?  If I purchase a set of p-ported housings, can I use the e-shaft and rotors from either my 1989 4-port turbo engine with it's 9.0 compression rotors, or the e-shaft and rotors from my 1988 NA 6-port engine with it's 9.4 compression rotors?  Or would I be better off using the street-ported 4-port center and end plates? I asked Paul Lamar, but I didn't understand his short answer.  He mentioned epoxy, but is that for the p-port housings or do you block off the ports in the front, rear and center plates that have the triangular ports in them?  Thanks in advance for all replies.  Unfortunately, I am not familiar with the internals of this engine, and how the stock porting works (or doesen't work) with peripheral ports.   Paul Conner
