AMS 2.3L or RNR 2.4L stroker ?
The reason why a 6mm deck height is better is simple... a taller deck height increases rod length. A motor with a longer rod has lower piston side loadings than a motor with a short rod. Less frictional losses, more linear power transmission, and decreased cylinder wall wear are all benefits. Typically a stroker kit will change the wrist pin location in the piston to move it higher, this is in an effort to get the longest rod possible in a short deck. The downside of this is a smaller ring land that is weaker and more succeptible to detonation damage. A taller deck height affords both larger ring lands and longer rods, which are all good things.

Without a doubt, use the 4g64 block.
I was under the impression that the evo 8 rods fit nicely with the 4g64 block & crank.
just buy weisco pistons & it's a dream. See below

They do, but then you are not taking advantage of that extra 6mm deck height.
