To answere some questions......
Always use you PPE ( personal protective equipment ) when using drills and realted equip.
This holds especialy true with strange women you meet at the bar....
Some of these clones using different size dowl pins on the heads.
This is I assume to prevent you feom using the smaller Honda heads on the Lonncin overbore blocks.
Drilling is best done ina drill press.
Use a metric drill bit for an exact match, but but an inch drill index is real close.
The point off the pins is to make sure the head is installed corectly and if you careful you can even put on a head without the pins.
