Point well taken. I have seen one pulled stud on this forum on a 2.7 with timecerts. It was a post from Wayne about using Casesavers instead of Timecerts. With Stijn's engine I think you are right and there is very little risk of pulled studs with the 2.4 nicacil cylinders.

I have my own little pet theory that we will start to see pulled studs on 2.7 engines with timecerts or even casesavers now that everyone is using steel studs instead of dilavar. I'm sure there will be much less than the original problem but enough to start being noticed in a few years. By the way I don't believe that the special studs (race ware, ARP, etc) will make any difference on this as they all are made of steel. The big question for me is will the stud pulls on mag cases with inserts approach the broken stud rates of Dilavar studs?

I used Dilavar studs on my 2.7 so you can guess which risk I think is greater.
