These heads are advertised as "aussie" heads on craigslist. I'm no expert, but I don't think these look like closed chambers? Is it just the gasket that makes it look like the open chambers? Any help identifying what heads these are would be great. Or any questions I can ask the seller specifically to nail down what they are. Thanks!
Closed chamber small intake ports I'd say he's telling the truth. Look carefully at the outline of the chamber around the valves. R.
Thanks for the input! I'm going to see if I can get a better pic of the chamber and the casting number above the chamber (does that number identify it?)
Thanks again. Thanks to you guys, I am taking a second look and probably going to pick these up.
What size intake valve do you plan to run?
The combustion chamber really shrouds 2.19 valves. Clearancing the valve will loose points on the static compression, but that's only part of the battle.
Just following up to finish this thread. Ended up getting the heads and camshaft. I'm learning as I go and hope these will turn out to be a good addition to my 351m. Still need to get a timing set, lifters, gaskets, and other odds and ends before I try to run it.
