You can purchase fully assembled heads directly from Ford.
Steve at Tousley Ford has the updated heads in stock all the time, They've gone up a bit recently but he can still gaurantee the best price on a set of new Terminator heads or head.
I believe its just north of $1900.00 including $300.00 core charges for a pair. Shipping averages about $90.00 for the set. Divide everything in half for just one head.
They are complete, loaded heads, full valvetrain and cams already installed.
Call them at 1-800-328-9552 ask for Steve or Kevin.
You sure about that? When was the head replaced last? The first 1 or 2 revisions to the '03 head did not have 9-thread spark plug holes. Does your current have 4 or 9 thread spark plug holes?
It was replaced by ford at est. 65 thousand miles .my passenger head has 4 threads.head shop repaired the head and did a 3 angle valve job for 500 dollars.the bad head has 9 threads .the same cyl was the bad 1 last time and it war an exhuast valve. What do i do with the half moon marks on the piston?
