I have 1.6 HS lifters and talking lash from the roller lifters into account I have right around .700 lift on both I and E. I can't wait to get this engine in my Demon but that will need a different (bigger for sure) radiator. I will be using 2 1/8 Mazzolini (TTI) semi-fenderwells.

I bought a World block because I heard too many horror stories about aluminum blocks not keeping the cylinders round without a fill. 200 lbs is a pretty high price to pay though for round walls. My 499 Keith Black block has a fill and seems to be OK but it gets warm driving on the street.
