R32 head design Mk4 - Mk5

[Treza360]

yeah ... lol .... interesting though, one thing that was confirmed (and I found elsewhere as well) was that the R32's compression ratio is 10.85:1 which will need to be dropped to under 9.5:1 (preferrably around 9:1) for me to proceed with my project.
Search for decompression plates currently under way ......
So far I've got a Garret T3 tubo, R32 cast turbo manifold & FMIC all ready to go .... now if only I could find a suitable R32 ..... lol

Some of this I can help you with. Please find below engine information. Aussie MkIV engine is BML, MkV is BUB.
