M50B25 timing tools

[malotas]

Hi all.

I´m currently in search for the tools for timing my 91 325i. I´ve found that they are very expensive, but then came across this drawings:

Could you tell me if this tools work for the M50B25 engine? (no vanos)

I could have them machined and spare a lot of money.

Thanks
