The only thing the M54 (3.0L) is good for is the crank! at 89.6mm stroke you can use it for a 3.0 or 3.1L M20.
The rods are 135mm, probably light but don't sound too strong.
To use M52 rods or not to use M52 rods, that is the question

Yup, went for the same as you, however I did make up a little spec sheet for myself and consider an 86mm bore for an extra 70cc but felt it was too much of a risk going for a larger bore.
Also considered selling the 2 M52 cranks I have and the ETA engine for a M54 crank and go for 3.1L on a 85mm bore. Which would still work with the pistons I ordered.
Went for the same spec as you, though I was qouted 8 weeks because of the ceramic coating.

Arrow rods from VAC

These Verdi ones from PPF in 130mm, 135mm or 140mm will do the job

ARP rod bolts are a must
