OK, so I've seen a few different versions of the blockoff, some use a freeze plug, others use expansion rubber plu etc. Anyone have experience with these under boost? I was thinking using the freeze plug with RTV and tapped into place might seal the best. I plan on running 10-15psi through this and don't want it blowing out. (Yes I could get an LS6 intake, or FAST, but it's a stock 4.8 right now and this is more of a testing phase for it, I have the LS1 intake).

The expansion plug I put in mine seems like it would hold up pretty good against anything. After I tightened mine down I pulled on it and tried to shake it and it never moved.
