My son recently picked up a set of W9 heads at a flea market. I don't know anything about them and was hoping someone could give me some insight. The casting number is P4532847, the heads have the ZAP logo with 2569 behind the logo. One head has scribed D5622-2 (6 could be G)directly under the logo. Under the valve cover on top of a intake runner is stamped 967839, the other head has 1049839 stamped in same location. They have been CNC'd and blended. The valves are 2.180 and 1.625. Intake runners have threaded holes for injection. I haven't measured the chambers as yet but they look fairly small. I also found a couple 51's stamped on each head which could be chamber size. I'll measure them soon.

RyanJ webb site says the ZAP W9's are rare but doesn't say if they're unique or just a few cast, any insight helpful. Heads appear older and have some marks and scratches but it looks like they've never been run on an engine.

Thanks, Max

I have a set of them, they're 59* heads. Mine have 53 stamped on them by someone. The ones I have are Zeus castings.

Zeus Aluminum Products (ZAP) was a common maker of the w9. Throw up some pics. Can tell alot more about what you have that way. Sounds like circle track stuff.

Rick, they did a 59 version, just hacked away the intake runner. Dont think you can tell them from any numbers stamped or cast into them from a 48 head. 59 versions can be un-ruined with a welder.

The 59 usually had the outer bolt holes shaved off though.

This is my impression.
The trenches cut for pushrod clearance are a dead giveaway on the 59 degree heads and it is a crap shoot whether the outer bolts were removed or not.
I have seen both.
I'd lean toward sprint car or road race with the port injection holes machined.
Nothing that can't be plugged.
I suppose they are worth scrap prices.......I'll even pay shipping.
When you say " flea market " I don't even think I want to know what they sold for.

The 2.18 with the injection holes are the sprint
car alky heads... nice heads.. cant say for fact if they
are 48* or 59*... its gonna take rpms or big cubes to
make them efficient... more than likely they flow about
365
