I agree here completely. When it absolutely has to work, spending less on less is absolutely foolish. The Time-Sert website does a good job explaining why.
I would say that in total, it took me at least 12 hours to do my 380 block (all 30+ holes!!!), and I can't see how a careful, experienced mechanic could do it in less than 6-8 hours, and I had the engine out.
I did do something possibly stupid - I wore the tap to the point where I barely finished the block, and the tools are not cheap and the tap is unique. I don't have the facilities to resharpen it. I used WD-40 as the cutting oil based on a website, and I now think that this was a bad idea, I should have used real cutting oil. OTOH, this IS high-silicon content aluminum and that tap and countersink tool wound up "cutting" a lot of glass.
