The stroker kit blows man ! youd be better off taking your block to a machine shop and bore it to 3,5. and upgrade your injectors and rings and rod bearings !
Port polish the head and see the difference ! or to get an idea, check out my profile or other posts, youll see what I have in mine.:gotnos:

It takes a 101mm stroker kit and a bore of 86mm to reach 3.5l.... and the cylinder walls are as thin as you could safely go. You can't reach 3.5l without a stroker kit.

With a stock stroke of 91mm you'd need a bore of 91mm... you'd be able to see through the walls at 87mm.
