Apex and corner seal question
 

I'm rebuilding a stock 88 6-port engine that will be mildly ported. I hesitant to use factory apes seals due to the wear characteristics of the factory seals. At 105,000 miles the rotor housings are junk.

What are the pros and cons of the different tyes of apex seals and corner seals available for a rebuild in my 88 13B N/A engine? How will these seals wear the new rotor housings? I'm interested in the one piece apex seals and the corner seals without the rubber insert if they are available in 2mm. This engine will be a race only engine for my F-Prepared car but I would like for it to last many years as I don't expect massive amounts of HP with the mild porting.

I have heard good things about the hurly 2 piece stell design. they are in all sizes. Check them out.
