I went to replace the thermostat today in my 3.5L. I've got an Edelbrock Performer intake manifold. One of the housing bolts broke off in the manifold. Thankfully, it was just the head and I was able to get a pair of vise grips on the remaining stud and pull it out without any damage to the intake manifold. My question now is what size bolts these are and if anyone has a part number?

1/2 Inch head, fine.
But that's from memory on s standard manifold.

Borrow one out of the timing cover, it will only leak a little more oil.

5/16" UNC 1"1/8 long or http://www.rimmerbros.co.uk/Item--i-SH505091 You would never find UNF bolts in an alloy manifold.
