[Fot] TR4 Valve Guide Clearance

[MadMarx]

I always asking myself why people going for these bronze type guides on a
cast iron engine?
There is no gain in power, only a gain in risk.
Once your engine lost its water on a straight your valves get stuck from
overheating and shrinking of the guides.

Bronze guides are very good in an aluminum engine but I don't see any profit
on a cast iron one.

More risk, more costs, more oil consumption with the larger clearance.
