Why stick with a stock stroke? I would go 4.5, by the time you pay to get a crank ground and new pistons, you are money ahead getting a stroker crank.
4.5 stroke
248@.050 .628 lift crane roller
StageV intake, heads, 2.3/1.9 valves, rockers
Quick fuel 770 vacuum carbs with annular booster
Milodon road race pan with external pickup
still cant afford to finish the car though

On your street and strip deal with no heads buying new aluminum ones are a no brainer That way you can pump the compression up over 11.0 to1 safely oon 91 octane pump swill On the rockers if you have cheap access to several sets of stock or one set of good blueprinted stock rockers then use them after checking the ratio at the retainers on all 16 rockers I went through 2 1/2 sets of stock rockers back in the day for my NHRA stocker, those stock rockers are pure junk as far as the ratio checked out to be They varied more than .110 lift at the retainers on both the intake and exhaust rocker arms on the same lobes with the same pushrods and checking springs on all of them
Hemiroid motors vcan bew challenging to get them in blueprint conditions so all eight cylinders have the exact same compression ratio, make sure and check the CC all eight combustion chambers before assembling the motor, I've seen 4.0 CC variations on one head Good luck, have fun
BTW,I've made more HP and torque per C.I. on stroker wedge motors than I have on Gen 2 hemiroid motors of the asme size and carb. CFM No kidding
