Re-Chambered 2.4L heads for 2.8L
Hi All, finally getting around to working on my '73 that had a tensioner failure. Rebuilding it with Mahle 2.8L cylinders and decided to re-chamber the heads rather than mucking about with shims under the cylinders. I drew up the head and valve seats then changed the profile from spherical to elliptical and chopped it off at the plane of the seats. The head volume is now 76cc. I used 0.010" step over on the CNC program. Here is a picture of the before/aft head:
