Hi once again, I am still on the hunt for an engine for my PT engined V8.

In the meantime, could someone detail the differences between the cylinder heads of the 3.6 PT and 4.2 ABH?
Some photos of the combustion chamber detail, for instance.

Thanks

85 WR quattro
90 V8 Silver, 91 V8 Black, 93 V8 Lago
93 100e quattro V6. Titan, i think
