59 Pontiac Mickey Thompson + GM Dept X Aluminum Heads
I came across these interesting experimental aluminum heads on my local Craigslist this morning and thought you all might be interested in at least seeing them. Sounds like they have a pretty interesting history!

Are those only 3/8” rocker studs?

3/8 WOULD BE BOTTLE NECK STUDS.
Those look like my 7/16 straight studs I had put into my 64 GTO heads many years ago. Looks like they were drilled but no oil feed passage under the studs to feed the studs and then the rockers & balls. For sure, pushrod oiling. Tom V.

There was already a thread on this heads on this site,non performance small valve heads.There were actually quite a few of them made,I have owned a few sets over the years.WAY over priced for the heads IMO.Tom

Why is the restamping below the cast in numbers a lower number?

Steve,as I recall that is the developmental number.If you look close on the valve cover rails the cc for each chamber was stamped on it as well as the D number.One set I owned came on a complete alu engine(less rotating assm).Mine was unique as the block had a 61-64 bell pattern and every other one I owned and have seen had 55-60.thad a flat 4 bbl intake and a alu timing cover.It was stamped as a 370 but had 3in mains.Was designed to run without sleeves.I found it at M/Ts back in 1964,took me a lot of years to get my hands on it.Put 60 over 350 size sleeves in it.It is running around in a 62 bubble top catalina last I knew.Tom

Looking at the intake face of the heads, there are 3 large holes where the exhaust crossover would be. I get that the larger centered hole is the crossover, what do you think the other holes are there for?

Those 7/16 Studs have a drill-hole in the side for...oiling.
Might be an oval hole entrance for block-head oil flow-up. NO provision for oill drainback except the pushrod holes huh. Last edited by Half-Inch Stud; 07-18-2021 at 09:32 PM. |
