I have a friend whos son has a Mustang and they are pullin it apart to make sure everything is kosher. I have a head question. he said after removing the intake and inspecting the heads everywhere he cannot find no signs of what kind of heads they are. they are aluminum and all he can notice is by using 2 mirrors up under where the intake would mount between cyl 3&4 and on the other side between cyl 5&6 there is the number 9035. besides that he said there is 2 header bolt holes on each side of the port, so each exhaust port has 4 holes. Can anyone give an idea to what heads these might be?

probally afr
Well what makes you say that? I am not lookin for a maybe. I have AFR heads on my car and they are stamped in big letters on the front of the head AFR along with the part number. Also I have never seen AFR heads with 4 header bolt holes for each port. Can you please expand on your answer?

the dual exhuast pattern narrows it down . Maybe world`s? but they have omthing machined in the front/rear of each head. This mkes me think maybe along the lines of pro topline or newer castings of pro comps, ford z series , along those lines . More infor on the heads would help . What size rockerstuds Intake port demensions etc

they are pro topline heads or as now known as rhs heads.



They were probably bought back when topline was topline thats why you probably wont find another part number like that anywhere b/c comp has owned topline for years now

Old Dart cast iron, I think some of the older world heads, Trick Flow R-series, high ports, Will Burt Street Heats.....Its hard to remember all of them.

I hear ya guys dont fight. They are aluminum heads with only the markings that I said. If they are Trick Flows you can tell by the valves right the Twisted Wedge design right? if so then they are not Trick Flows, the valves are in the standard position.

Yea, but not all trick flows are the twisted wedge design.
