anyone have any pics of how they tapped the head. the bigger hole is a solid cylinder shape and will easily take threads and seal. however i dont know if how the smaller hole, being so thin if it will properly seal or if anyone had any pics on how they did it. i dont want to rush into things and would rather see first hand. thanks.

I thought you were not supposed to weld it shut?

didn't someone have a bad experience doing that?
I thought i was told that that port was critical to coolant circulation?

Ok.. Someone had problems when they plugged it because shavings got to the motor.

If you weld it shut, you have to route the water another way to it get to the thermostat. I would recommend against shutting it but a few people that have done this, have no problems with it.

is this a picture of the finished product? didnt look into welding the head since its aluminum, and could warp.
yeah, but if you put your finger in the hole you will see that there is not a lot of material to thread

This is what hasport made but it is not yet for sale



maybe you can make something like that?

The RBC mani seem to work but I think its on the small side for this big of an engine so we are going to make our own for next year. I run NDRA C4 so I have to stay with a mani, although I would love to see what it would do with ITBs. My RBC mani and overbored TB will be for sale in a few weeks if anyone is interested in them.
