New Stroker Build

I'm new to this forum, and am looking for some answers on how to build my stroker for my 1999 wrnagler.

I started with a 99 block from a cherokee, and got a Clegg stage 3 kit, which includes Icon forged 21 cc dish pistons, forged 6.125" rods, switched to hastings rings and king bearings for the rods and mains. I bored out the cylinders 0.030" over. I then went with their stage 2 cam and valvetrain kit, with oversized valves, and the cam has a duration of 269 intake and 273 exhaust with 114 lobe separation. For now, I plan on keeping the stock head, which is a #0630 head and redoing the valves to accommodate the oversized valves, as well as a DIY port job on it.

Does anyone see any issues with this combo or have any advice for building this stroker? Ive also been trying to figure out where my C.R. will actually be, but the many calculators (including on here) have been giving me some different calculations. Anyone have any ideas?

Thanks in advance!

Assuming the block isn't decked, the static CR will be ~9.2:1 with a quench height of ~0.070".
You might want to consider having 0.020" shaved from the block deck to reduce the quench to ~0.050" and raise the CR to ~9.6:1. This will reduce the engine's propensity to detonate and add a little performance. Before ordering new pushrods, get a pushrod length checker to verify the correct length.
