Quick question to the guys using a later model 4.3 in their trucks/cars.

What did you plug the holes in the sides of the heads with? It looks like there was a knock sensor or a temp sensor in there. Its got a weird thread and I didn't want to strip it out trying to plug it. Is there something someone can suggest? They're the stock Vortec style heads if that matters.

Thanks

Haycock, are you running the stock style serpetine belt set up? Or something different? I've got the parts to cobble it together a couple
different ways, just havent figured out the best way yet.

And thanks for the reply, I'll just do my best and try and thread something in there.

yea im running the stock serpetine setup except on the A/C-P/S pump bracket i cut the A/C part off and ran a shorter belt. i was originaly going to make all new brackets to try and save some room but i got lazy and used all the stock ones and it worked out good.
