I gambled and maybe I
I have a 49 f1 I got a 89 e250 302/efi for a donor it had a lot of miles so it's got low oil pressure 6-9 psi (15-50 oil)at idle and makes a little noise at start up rear main oil leak. So I'd like to know what your opinion is for replacing, rebuild or ?
I would like 200 plus hp should I do it myself with your help, just get a crate from who any ideas

You don't need heads to break 200hp just a cam. I say strip it down and send out the longblock to a machine shop, If you can find a decent shop that will work with you and just do the work that the parts need(these Ford blocks don't need line boring or decking), then you will just have to spend money on bearing surfaces, bores and valve guides. Then put it together with an aftermarket EFI friendly flat tappet cam like the 31-255-5, or convert it to a roller setup with valvetrain parts(cam. lifters, pushrods, spider) salvaged from a '94+ junkyard truck motor or 5.0HO, and you will have 250hp give or take as long as the exhaust system isn't a complete cork.

I was hoping you would say something Conan I would like a roller cam, I could get headers but I don't want noise in the front it's not very noisy now without carpet and want to keep it that way. As for aluminum heads it would be more for bringing the wieght down on the front and 40# is going to make up the ac I added although not mandatory

Another question on this 302 my engine is from a 1989 Efi would like to keep the efi and the pcm so if I change to a roller cam change does that change the firing order to 137 From 154 and then do I change the pcm and the map and FI
By the way I probably dropping the aluminum heads to much $$
