Hey Guys, I have a 2000 GT with a warped valve, (long story) Anyway i found a set of heads at a pick a part today. They are RF-2L1E-6090-C20B. Will these fit with no problems on my engine? They are in great shape. They are on a truck 5.4. Anything I should look for? Combustion chambers the same and so forth? Everthing bolt up?
