I'm about to convert my TGB13 to run on unleaded an take the compression up a notch at the same time. I've been advised to skim 2mm off the head wich will release an extra 15%-20% extra power. This will allow the engine to best use the LPG which it normally runs on.
Any comments?
More power!!!

Have a machine shop put some harder valve seats in the head.
The CI head and the directly cut valve seats are not too resistant to torching. Since the head is coming off it makes sense to upgrade for possible future unleaded petrol use and the higher anticipated temps likely with a compression increase.
Thats why we always have an exchange head in stock for those wanting to stop pinking and detonation a symptom particularly present on the B30/ c303 series install.
