I have a 91 that I installed an E303 cam, explorer upper & lower intake, and Hooker equal length shorty headers, H pipe, flowmasters. The engine has started to blow bubbles so I need to pull the heads. Are the GT40P heads worth buying? Will I have any fit issues or spark plug clearance with the shorty headers? I changed the head springs to Lazers when I installed the cam. Will I need to change the GT40P springs and will my Lazers work since they only have a few thousand miles?

you will need to change the springs off your gt40p heads, as they wont handle that cam. the gt40P heads require different headers, or short spark plugs(although, no one can seem to come up with a part number for them.) they are decent heads and if bought for the right price can be worth it. your setup is pretty similar to what i am running
