When I bought my T-Bird last year, I wasn't smart enough to check the cylinder heads on the car. Turns out they were 292 C1AE heads. In searching for correct heads (ECZ-G), which are hard to find or expensive if found,  I came upon 292 5752-113 heads and bought them. Has anyone used this heads on their 312? I also got OEM high ratio rockers to compliment these heads.
