Engine porting

I did a bunch of research on apex seals and i've basically decided to stick with the stock 3 piece 2mm seals too... although ceramics have their benefits they only come in 2 or 1 piece so they don't seal as well as the 3 piece.... although it would be nice to not have any seal float > 8500rpm.

Wholy ****.. damn I was in Guam for the last 4 days so I missed all this...
I've always used stock apex seals, but we're trying Atkins 2mm seaks in Igy's car right now and they seem to be kicking ***.. I plan on using them in my engines in the future... Here is some good reading on porting...
****, why can't I add a attachment..

Are you sure it's not 130 PSI? 150 is quite a bit more than stock.

I will bring this back up just to explain what people mean when they say "you don't want to much over lap" Ok see where the groove in the face of the plate is that is labeled corner seal track. See how it just barely grazes by the top left corner of the port. If that port is made too large and the over lap of port and rotor is to big the corner seal will get sucked into the intake port and boom .. bye bye engine.
I was asked this the other day by a forum member and I had to ask someone myself to make suer I got it right. Makes perfect sense to me now and hopefully you too.
