If you have PayPal or Venmo dm me I'd love to buy you a beer. It's amazing that my original estimate was so close. 8th digit of my vin is V so I'll probably opt for the E85 route, here in the Midwest it's at every 3rd gas station, 100 octane baby!I do everything in metric:
88.9mm bore (3.5")
79.8mm stroke (3.14)
1.65mm head gasket (0.065")
49.0cc head chambers
50.0mm x 0.81mm dome on pistons (its a thin cylinder)
1 cylinder = 495cc
head gasket = 10.2cc
Compression Ratio aka CR = (495+10.2+49)/(495+10.2) = 9.35 (same as historical)
Add in the dome
CR = (495+10.2+49-1.6)/(495+10.2-1.6) = 9.59 - the domes on the Taurus pistons do increase the CR, but not bloody much
.75 mm decking of heads (even figuring the combustion chamber is a rectangle of 88mm x 60mm)
CR = (495+10.2+49-1.6-4.1)/(495+10.2-1.6-4.1) =10.24
At ~10:1, @MankDeems3.0 can probably still get away with just running premium.
With only a $0.30/gallon difference between regular and premium, assuming Ranger gets 15 mpg, its over 25k miles to pay off a $500 commercial water injection system (not including the additional windshield washer fluid).
Aside: With the decking and dome you will want to check valve clearance.
I'm chaising a charging system issue. New ground strap, alternator, battery, all since I built my heads, none related. I'll post more when it's tracked down, I'm still dying to see the final results!E85 is the easy button. Runs cooler. Eliminates carbon buildup. Has plenty of octane (usually). Cheaper than Premium. Just make sure you've got enough injector.
There's a mile of piston to valve clearance, even with 1.7 rockers. I did a clay test on mine when I put it together, and with about 1/4" of clay on the piston, the valves didn't even make an imprint.
A cam would be nice. You'd really want a nice valve spring upgrade though with rockers and a cam. Especially if you spend any time at high rpms. The 1.7s alone might be enough to warrant the spring upgrade.
I don't think some port work, a small compression bump, more valve lift and E85 are going to get you 50+hp, but they'll probably make the truck more enjoyable.
I know they respond well to mods. Ive done an E-fan, exhaust, & ported the maf meter & put in a k&n filter. Its much peppier than it was before, i can actually accelerate & merge into traffic without getting kilt. Lol. I have a ported upper/lower intake from an '02, 1.8 rockers, and underdrive pulleys to add soon. Debating on getting a set of new heads & doing a bit of port work. I'd like to do a cam, but Ive only found one place to get one & that guy stoopid high on his prices.I'm chaising a charging system issue.

The main goal of this project was to find out, if a guy found a 3.0 ranger for $500 on Facebook with a cracked a head or ya even blew a gasket. Are the "While your in there" performance mods going to make your Vulcan a better engine day to day?
My working theory is a single reman head is $375. I got 80K mile Taurus heads, got them tested and resurfaced, Motocraft gaskets, head bolts and fluids for about $550. If you're already in there and spending that much you might as well spend the extra $200 on a used throttle body and rocker arms and make it a little more drivable for the same price as the reman heads at $750! We'll see what the butt dyno says. If my ass is really impressed I Might even bring it over for 3 runs on the rollers at my local speed shop once it's all done
