I think my engine has two secrets.
First, the flywheel runs perfectly true on the crank.
Second, my clutch arrangement is very light. Titanium made.
I run the same stock bolts for now 17 years.
I think a dowel pin is not needed as the camping should be sufficient.
I question the use of aluminum flywheels.
Aluminum expand when hot. The bolts are short. Maybe they stretch from this?

Betreff: Re: [Fot] TR4 ARP Flywheel Bolts Question
Being serious for a moment on this issue. I ran with the standard arrangement
of 4 bolts and 1 dowel with a stock crank and lightened stock flywheel for a
while on my rally TR4, which only revved to 6500 rpm maybe, so you'd think that
would be ok. Not so, even with new bolts and dowel continued pulsing of the
engine between 5000 and 6500 caused the bolts to stretch. I didn't have tabs on
at that time. Last time I ripped be flywheel off was on the way home from the
petrol station, so wasn't even on an event and trying for anything.?
Jacks solution works for me and I'm continually crossing the 'wobbly zone' in
the rev range (albeit quickly). 4 dowels would be optimal.
Keep it straight.
Tony?

But Chris is that crazy fast German that only turns the engine in his TR-4 to
six grand but still runs away from everybody that are turning to 6800 and over.
?:-) Therefore his comment does not count. ?:-)

I use a steel flywheel and the 4 factory bolts.
To keep them in place, Loctite red.
