99 Ford Windstar Compression range?

I have a 99 Ford Windstar 3.8L V6 with 155, XXX miles. My husband has noticed coolant in the oil and oil in the coolant. We think it could be a head gasket issue but not 100%. Van still drives but has lost its power. Upon doing a dry compression test we got the results cyl#1 190 cyl#2 190 cyl#3 200 cyl#4 205 cyl#5 205 cyl#6 210. Then we did it wet with 1=240 2=260 3=240 4=225 5=270 and 6=230. According to the chiltons this means there are worn rings since compression came up when it was wet vs dry so hubby thinks its time to get a diff engine and rebuild this one as he now believes the cylinders are worn but wants it drivable as soon as possible with the original rebuilt as a backup. Also in the book it says two adjacent cylinders with equally low compression means bad head gasket and specs say 101 minimum compression. I'm confused as to what is an acceptable compression range and is it worth it to purchase a good used engine versus fixing the head gasket(s). I'm basically lost any input is greatly valued.

How much horsepower should a 410 v8 make?

How much horsepower should a 410 cubic inch v8 make at 10:1 compression?
I'm building a ford 400 V8 with stock bottom end 4" stroke with stock 6.58" rods bored.040 over for a total bore of 4.040" and decking the block with zero deck/piston clearance with stock 74 cc open chamber heads with polished runners and gasket matched and a crane cam p# 523901 conventional flat hydraulic tappets which should put me right at 10:1 compression. An edelbroc performer 400 Dual plane intake manifold with 1" open plenum carb spacer and either my Holley 600 cfm 4 bbl or my 750cfm quadrajet. I'm putting long tube headers with an open exhaust 2.50" to glasspacks.
I was thinking It has the potential to make 1hp/ cubic inch so around 400 HP is what I'm shooting for in this build. Until dyno runs I won't know exactly but I was wondering whether anyone had any sort of idea of how much HP/ TQ this engine could make with my setup.
