After an exhaustive title search and death threats to the PO I got the 20R head from.....
Please do yourself a favor and get you about 4 feet of threaded rod.
I just probably broke BOTH the T-stat bolts off in the only 20R intake in the state

, result? wont ever happen again!
tomorrow I'm going to Lowes, get me some rod(threaded rod you schmucks!), some locktight and some of those washered bolts that wont sink into the socket, and by golly I'm stud'n her out! THIS WILL NOT HAPPEN AGAIN.
Every engine I ever tear down from this point on, stud's will go back in their place.
Like this,
