Very nice bits! That oil tank looks like it holds MUCH more volume than the stocker.

I don't see any detrimental effect.  The increased volume and cooling surface may keep your oil temperature down.

Hi I'm getting ready to build my engine back up .I've read a few things about how to prevent oil leaks one of the things I'm not sure about is the 4 notch pins in between the head &barrels I've had my head skimmed but not the barrels .do I have to file them down or will it be ok with not having barrels skimmed .Cheers yozzer

Really nice work. I think I will make something similar to your rears holders. I already measured some things needed to design rears holders. By my measurements thickens of standard f2 holders at bolts holes is 24mm?
