Can anyone tell me what the numbers on the head mean?
Aftermarket Head. It must have made some power cause they have added water pump to help cool the motor. Scott
Wonder what the combustion chambers look like?
Older post on this type head:

I have an aluminum head that I removed to reduce the exhaust smoke and oil use. This one had 95 psi compression on two cylinders and 65 psi compression on two cylinders. The 65 psi suggested a leak between two cylinders, but I'm not sure if 95 was normal or high. I'm also not sure who made the head. There is Made in U.S.A. on it and also VTH-1000H and 20-27 near the back driver's side.
Found the maker, Totally T's here is that head on their webpage.
I run a head like this on my Roadster. Snyders sells them and they do make some good power. I don't run a water pump even with this head.
That is a Ralph Reeder head from the no longer existent Performance T Parts in Dickinson Tx, I run them on at least 10 cars. I have no problems with them.
As Jeff says, a "Reeder" head. Very much like an aluminum "Z" head in design and performance.
