Is the bottom end of this engine in good shape? Did you do a compression test before you took the heads off?
You guys should stop with the flywheel talk.
In 99.9 percent of cases it's not provable.
gt40 iron heads with a cam and gt40 explorer intake will make 250-265rwhp. That's really not opinion, it's been done thousands of times.
TFS kit will make 290-310rwhp. Again, i consider this to be fact.
It goes up from there, custom cam's, better intakes, afr heads you can stretch it all the way to 359rwhp (which is the best i've personally seen from any stock 302).
Electric fans should not be any type of priority on a gt40 iron setup, if you have an extra $400 it should goto the heads long before that. You have the best parts already? Go ahead, just don't expect a lot of return for your money.
For the OP, what makes you think the heads are the problem and the engine isn't burning oil?

Low-ish compression isn't necessarily rings.The compression is at the bottom level of ok, not really good but ok. I would throw some bearings and rings at it.
I agree but we don't know the miles, it was just my opinion.Low-ish compression isn't necessarily rings.

Which would beg the question, why did an 80,000 mile car need new rings and bearings, when they typically last at least twice (sometimes triple) that?Just spoke with previous owner. It had new rings and bearings less than 20k ago.
If the GT40 heads give me 30hp, what do a set of new heads give me? I know it varies, but a general range would be good.
I'm good with efans, like I said I end up putting them on all my cars but I don't do it as a first mod or to pickup horsepowerI agree with you Boosted on most of what you said. On the efan front... I can teach you how to install used Contour fans with parts from the wreckers, not hacking the wiring and the only not plug and play part is connecting a fan control switch from your favorite OEM. Will need to fabicate a T-connector for the lower rad hose and total cost should be well under $100. You will have OEM reliabilty and electric fans that barely run unless in stop and go traffic and a pair of override switches if you like too.
I just did my '04 F150 using a fan unit from a 2010 and OEM Contour relay system (just like I did my Mustang). My total cost (because I had some left over Contour parts from a 4 cyl DD) were around $70 CDN.
