[QUOTE="cobraracer46, post: 1160203, member: 18298"] I would advise to clean up the cylinder heads and resurface them only if they need it. Putting pi heads on your car will raise the compression to 10:1 and cutting the heads will jack up the compression even more. Get a head changing kit from Ford Racing.
