Super Jet Installing 850 sleeves. porting boost port?

[SuperCarlus]

What's your opinion?

I'm installing 850 sleeves from Blowsion in 62T cylinders. The 62T case is epoxied and highly ported. With the sleeves installed, I will port exhaust ports and clean transfers. But I don't know if I should open the boost ports of 3 mm before... I would like to have good bottom end.

I would contact the lead tech guy at Blowsion because they have 3 yrs R&D into building topends with these sleeves...I think his name is Eric...Also Chuck at XS just built two of these same topends recently for a friend and myself, so he should have great insight also. Mine pulls hard with a solas mag and 10/16 hooker ...good luck.

should I put JB-weld in the free chambers of the cylinder to reinforce the meat and sustain the sleeve??

epoxy there will not help.
