Can some tell me what the consequences/and or rewards are of raising the cylinder 1.5mm to help piston to port timing?

more time to clear the cylinder. Better torque and better high rpm flow. I'm sure someone will chime in and get more technical than I have.

Well with raising cylinder 1.5mm, intake port completely open at tdc & on exhaust at bdc the piston barely covers exhaust port. It just looks better in my opinion.

I use two base gaskets, looking for thicker ones so I can reduce leak chances. I'm trying to get mark20 the gasket man on board, lol.

Yeah I hear you there. I made my own base/ cylinder gaskets, cause everyone i bought fits horribly. Made gasket to match cylinder then modded the case to new gaskets.

I have no clue where to get them, but I found these green gaskets that really kick arse. I used the last one, looking for more. They fit perfectly to the jug, and like glue themselves to the parts after a heat cycle. They are super nice. I wish I could find them again.

Like these ones? yes there awesome, they fit great, & that's what I matched case to. I ordered these thru cdh off of amazon & were in cdh labeled box.

YEAH, THATS THEM!! Sweet, an they come from my vendor of choosing. lol. I was wondering why I only had two or three of them. Must have come with jugs or something. They seal the best I have ever seen in al of the gaskets I've tried. The next best are the tar paper gaskets. I have a ton of those.

They had them on amazon in 2packs for $5 something. They had 10 packs also but I can't seem to find them now.

In regards of them green base gaskets, I found that exact material in bulk, I've used it before in high pressure applications, look up, Sterling seal & supply #7001-nsf-61 that's good stuff,
