Head questions???

Ok guys i have everything planned out.. So i am ordering a 2.3 head from ebay here is the item number 170913248841. Will this work? I called.the guy and he asked for the cast number i told.him what i was doing he said thats crazy and he asked.if.i had vvt? So i need some help does the cast number matter and do i order a head with vvt? And does any body know what.the stock compression ratio is for my 2011 2.0? And one last question when i get the 2.3 head after i get some feedback on what matters and what options to get then i am going to send the.head to machine shop to mill how much do i take off to raise the compression ratio to where i dont hit piston and with spray dont unload the bottom end? And as for cams i have heard alot about the crane 224-0010 i am planning to do aftermarket cams on the 2.3 head these 224-0010 still the way to go? If i can go bigger will it effect hp/tq? Just looking fir the right cams for my set up so any input will be great thanx...

If you mill the head you'll raise the compression. The crane 0010's are a mid range. For you going a 20 motor w/ a 23 head, I'd use those. You could add the 0012's, but you'd lose some bottom end grunt. 1st you have a 20 & then 2nd installing a 23 head on a 20. I like spray too, I just don't like running out & dealing w/ refilling the bottles. I'd cc the chambers & compare the 2 heads.

Why would you need to raise the compression ratio to run nos?

You should look for a PN on the exhaust ports side of the head.
RF 1S7G is stock 2.0 head (and Ranger 2.3).
RF 3S4G is the one with better flow.
