Is the PCV valve in use ?

Gap them correctly and they work fine. I have put them on some very questionable bores and have had great results.

I use them regularly, they are about 35 minutes away. Nice product.

So the crappier the chamber the less it matters?

Yes.

From what I see, it looks like the corner bumps should be removed and quite likely leaned out.

Wow, those pictures are great. Thanks Chad, I can see to some degree how you are making the runner length more equal. You and others have shown me much by pictures and dialogue that I can understand.

I get them from Competition Products, but I'm sure you can find them through Summit or Jegs.

For what it's worth. The combination I had was an SRP 4032 Piston that was 420 Grams, plus the rings pin and clips, don't remember those numbers. 5.7 Scat, proComp rod for strokers, 5.7 length on a Scat std weight 9000 cast crank. Externally balanced.

I know it's. 002 different, but I run a .036 at 7200 RPM with same material and no problem. I think your combination will peak a fair amount lower.

Yes
