During the 25 years that I was racing a TR-4 I acquired many parts cars to support my racing hobby. When I parted out these cars,m I kept anything that could possibly be used one day.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Cylinder head studs: I've heard lots of theories about them. Everything from "you must change every time you rebuild" to "keep using them forever". My actual experience is closer to the latter. During the time that I raced, I never bought an engine stud (cylinder head, or otherwise). When I disassembled an engine, I inspected the cylinder head studs, and unless there were major gouges or other obvious defects, I kept the studs (5 different lengths). I used, and re-used these studs through 25 years of racing, and lots of hours in street cars, and have never had one break. That's the only evidence I can give for the quality of the design of these studs.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">So now, I am cleaning out my garage and I have a lot of head studs, as follows:</div><div dir="ltr" data-setdir="false">. 48 - 9" studs</div><div dir="ltr" data-setdir="false">. 21 - 9 1/2" studs</div><div dir="ltr" data-setdir="false">. 71 - 5" studs</div><div dir="ltr" data-setdir="false">. 39 - 5 3/8" studs</div><div dir="ltr" data-setdir="false">. 12 - 5 1/2" studs</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">This last one (5 1/2"), is the one used at the passenger side rear corner of the engine, on engines starting with the TR-3B through the TR-4A. It is slightly longer than the other short studs on the right side of the engine, to accommodate the lifting bracket which attaches to this stud.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I'm trying to figure out what to do with these studs. I could take them to the scrap metal yard, and get pennies per pound for them. But that is a difficult step for a pack rat. So, anyone have any ideas? Because of the weight, they are expensive to ship. I'd be happy to give them (or some of them) to anyone who has a use for them. The FOT has always been helpful for me in the past, and I'm sure you will come up with something this time.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thank you, and best regards,</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jack<br></div></div></body></html>
