The heads I will be using for my 5.0HO (from an 87 GT) are older but were apparently a decent head in their day. Better than stock anyway (plus they were free from a friend
The heads are aluminum Ford Racing M-6049-J302.
Here's one bit of info I found on another board...
30 hp increase by just swapping from the E7 head
50-60 hp increase by swapping heads and intake
100-110 hp increase by swapping heads, intake, headers and proper cam
1.94 intake and 1.60 exhaust valves (2.02 intake/1.60 on K302)
drilled and tapped for screw in rocker arm studs
accepts stock valve covers, intakes, and headers
exhaust flange has dual bolt pattern for added room for porting
combustion chambers are 58cc
intake port is 170cc
exhaust port is 60cc
uses Motorcraft AG series spark plugs
My questions are:
Does anyone know anything about header selection/fitment?
Any other info you may have would be helpful.
