Ok guys but I was told...and this makes sense by the way.
The coolant lines that go to the egr valve does indeed warm the incoming air, but also cools the egr valve once the car has been running for a while! The exhust coming from the heads go to the egr valve (emissions thing) so you need to cool the temp at the egr. Now people normally just by- pass the egr valve thinking that they are doing a good thing but they are not. Well untill you block off the passage way from the heads. I have seen people use a steel shim between the intake and egr port on the heads. But I like the using a freeze plug that goes into the bottom off the upper intake. Now when you do this, they're will be no exhust gases going to the egr valve and hence no need run coolant to your egr valve. Now not all heads have egr port in the heads. The race heads don't come with egr port (passage or what ever you want to call it) so you would not need to block anything.
As goes for the oil going past the baffle, I agree with exgmguy, it goes past the baffles... you got blow by. But you have to expect some blow by on these engines we are running. It seems that a lot of people are starting to worry about little things. Stop worrying about the SMALL STUFF...&...RUN IT!!!!
Hope this makes sense, sorry for any confusion.
