Liberty cylinder heads?

[travis]

Does anybody here know anything about these? I just stumbled across these but have never heard of them.

I used 1 set of those on a mild 351W for an old pickup truck.

249cfm @ .600 lift intake, 146 @ .600 lift exhaust on my superflow bench

Ex port stalls at .400 and never recovers.

China casting but light years ahead of a pro comp / speedmaster.

You'll have to touch up the guides and valve job just like any other head you buy.

Thank you!

That exhaust port doesn’t look very good...

Is that Liberty Engine Warehouse?

Liberty sells castings imported through Proheader I believe as well as other importers.
The castings are a Dart platinum reproduction.
I have been buying from Proheader for at least five years. The heads work well.

That’s good to know. I’ve been eyeballing some of Eric Weingartner’s budget ported Proheader heads for a relatively low buck 408w I’m putting together.

How deep are the seats and are they interlocking?

Here is my ad on craigslist here in Phoenix.

Yes the seats interlock. When I get out in the garage I will measure the depth of the seat. They look like any other name brand seat.
If your wondering about the name Bruco Performance, people are real funny when they don't recognise the name of the manufacture.
When I advertised the heads as Proheader no one was interested. Once I changed the name to mine I have had much more success selling heads.
