need help presistant p0304 engine code

alloro, how much would it cost to do that? I know each shp charges what they want, but do you know of a baseline?
Also, should I just do 1 head, or both? the codes I am getting are P0304 and P0300
worst case scenario, car-part. com has used heads for $150 (not sure if that is one side or a pair)

I would get both heads as if one, at 200k+ miles has failed, the other isn't very far behind

P0304 bothers me when the weather is damp and I don't drive it everyday...
I reset and don't see the code again for months as long as it is warm or I drive it everyday
get a cheap scan tool from Harbor Freight when they go on sale
I have two from them and keep the cheaper one in the van to reset the code
I have 193K on my 5.2L

adjacent cylinders under pressure will leak and have lower compression with a crack then cylinders without a crack...
the compression test also tells you if your piston rings or valves are leaking
in order to test good all cylinders should be within 10%
take the measurements, write them down indicating the cylinder and post the numbers...
don't remove anything until you do this simple test...
pull the plug from the coil as you don't want the engine to start
pull a plug, screw in the gauge, then crank the engine a few seconds while someone looks at the compression gauge... note the top number you achieve, then also note how fast you lose 1/2 of that pressure in seconds... replace the plug and repeat on the next cylinder
