Nothing is ever easy. I thought I the alternator and power steering mountings worked out using the 461 heads (no holes)...wrong. The PS pulley was not going to clear the steering box and the balancer. Long story short, I had a set of fresh 441 heads (with bolt holes) I had drilled for steam holes. Thirty-four bolts out, 34 bolt holes chased, 34 bolts in and voila I could put the PS pump up higher.
My compression is lower but should still be about 9:1, still ok with the XE268 cam.
