What's the concensus on this? Anybody prefer solids vs. stock w/ the rubber insert? I've tried both but not sure which is better, quite honestly.

Hey Brian. I don't know which is better, but when I use carbon apexes I like the thought of the extra support that the solid corner gives to the apex.

I have always wondered about this subject myself. Considering that the stock corner seals were made for three piece apex seals and many of us are using 2 piece aftermarket seals in our rebuilds, an engineering research paper appears to be in order. Anyone care to do the honors?

 

Hanging around IGY and Dragon, the general consensus is that stock corner seals work fine. I know that IGY bought solid corner seals for one of his bridgeport motors(I don't know the manufacturer) and they wore down very quickly. I know that Hurley makes a solid corner seal with a built in spring. I may try these out to see how quickly the wear down.

I've been running the stock corner seal with the rubber peice removed in a **** load of engines... most of them making over 400hp with no problems ever. I would suggest doing it like that.

 

With a 2mm seal? Wouldn't there be too much play?

 

The corner seals with rubber plugs have been used with both 3mm & 2mm seals. The plug has nothing to do with clearances only to help seal better when staring hot. For a street car it's a good idea.

 

That was my understanding: The rubber insert is there to help hold compression, especially on start up. They seem to work too.

Until it falls into your port getting wedged and blows your motor. Fine for a stock motor, will fall out with a big sideport.
