The Stovebolt Site Forums The Shop Area Engine Shop 230 manifold stud

Hi
I am currently stripping down a 1964, 230 for rebuilding.
And noticed while removing the intake/ exhaust manifolds from the head there was one stud and the rest of the fasteners were bolts with alignment pins on the ends
I am guessing this was due to someone stripping the threads. As I found a helicoil after I remove the stud from the head.
I like the idea of having studs instead of bolts and was wondering if anyone sell a stud kit for the manifolds

Also this is my first rebuild on this type of engine and I have the power book but would like to find reference material that cover a stock rebuild.

Does any one also know of a good machine shop in the Panama City Florida area? I need to get the head clean ,inspected and pressure check.

The third position from each end had studs in them. The rest used bolts.

Here is a link to a GM service manual, Pontiac, Olds, and Chevrolet all used the same engine.

Studs are easy to install and are nothing fancy, any local hardware will store will have some that work. 1.5" long should do it.

The two long bolts should stay, the end pins are threaded and can be removed with vise grips.

Follow the manual when tightening the head bolts, except the left front bolt only needs 75 ft lbs where the rest go 95 ft lbs. The block will break if over torqued.

Thanks
But what is the the reasoning for the two long bolts vs studs?

Nothing really, it's just studs that long will not look as good as a smooth bolt would in my opinion, but thats just me. I used polished stainless steel bolt and nuts on my, with custom made stainless hold down on the two long bolts. I like them shiny!

Thanks I will keep that in mind
