same here.

Also I don't think its a huge gain. Maybe 3-5whp at most. Dyno before and after and let us know

Always a good idea to listen to Miko. Guy knows more about these motors than any 50 of us put together. Call or email the thermoblock folks, they don't list them but they're happy to cut them for the VE; they did for me couple years ago when I put her together. Probably helps keep things cooler, couldn't tell you whether a hp difference, as didn't dyno before/after.
