302 oil pressure

changed out the heads on my 302 ford. Runs good but oil pressure is now really low. Checked with a second gauge, same reading as the old one. What is going on?

 

Did you only change the heads? Nothing else

 

other than oil and filter thats all. Same filter that I was using before.

 

Gasket blocking a passage?

 

Are you using a mechanical or electric gauge?Ithink you may have gotten a tiny piece of crud in the pressure port.There are no pressure passages in the heads except for pushrods.You also could have gotten alot of crap down in the pan and it is blocking the pickup.

 

Try a different (new) oil filter (you could have gotten a bad one), provided you didn't get a lot of crap in the pan, and pick up tube like 65comet suggested.
