I can totally understand why the heads are different as the engine was built specifically for a Torana 15 to 20+ years ago.
The engine was originally built by M.R. Automotive many many years ago which I did contact them regarding the 308 although they couldn’t give me much info as I didn’t have a previous invoice or rego number... Anyway the engine has had some time spent on it with the heads ported quite well, big valves, the valley de burred, oil galleries opened up, Chev pistons and running a decent Cam, 10.5:1 Compression.
