Simply stated, pushing coolant may be common, but it's not acceptable, and it's not a good thing.

What you have to realize is that what is getting pushed into the coolant are extremely hot gasses which over time will eat away at the head gasket and make it worse, call it a snow ball effect. Some instances will have eroded the block and head in that area if its bad enough.

If the tune is good, then I would suggest better studs than what you have now. If I remember correctly, the basic ARP's are only good to about 30 psi anyway, so get something better like the A1's or ARP L19's. May cost a little more now, but will save you money in the long run.

Also, I wouldn't use Rau's blowing a head gasket as anything negative about the A1 studs, he runs extremely high boost and cylinder pressures on that motor and eventually somethings gonna let go. In most cases 2 to 3 times the boost most DSM'ers run on their street cars.

I have the A1 studs. Is it overkill? Who knows? I don't think so as I plan to run 35-40 psi at some point in the near future. Just one less thing to worry about for me.
