got new heads, what are they?

[blk9450]

ok so i got these aluminum heads but i dont know what brand they are. they have stamped by the valve cover 6 a star then 99 which im assuming is the production date and by the exhaust valves there is a serial number sn35526-2 on the passenger side and 35530-2 on the driver side head. the valves seem to be 2" intake and 1-5/8" exhaust. the roller rockers also say f72 on them but nobrand. anybody have any ideas? they look exactly the same as trick flow twisted wedge picture in summit. i have pics i will post later.

Can'y say for sure but the serial #'s look sort of like trick flow s/n #'s. The reason that I say this is, I still have one of the stickers that came with my heads and it is s/n 35523. Call trick flow and they should be able to tell you.

my heads have trick flow machined into the front of them

ok well ive determined they are twisted wedge heads, but i still dont know what the rockers are. they are anodised aluminum stud mount roller rockers with just a "f72" on the top. i really dont care what they are i just want to know what the ratio is. is there any way to measure this?>

maybe the f72 means 1.72, but thats just a guess/shot in the dark

 

[blk9450]

yea thats what i was thinking, but i am hoping they are 1.6 : 1 im worried about p/v clearance

how did you come by a pair of heads and dont know what brand they are?

believe it or not, i got them at the junkyard, all they said was aftermarket alum head for 91 mustang with aftermarket rockers.
