car stuttering when i accelerate some times it does it before is warmed up no smoke come out the exhaust could it be a bent valve or what lmk know what you guys think thanks

 

when was the last time you changed your spark plugs??

 

about two months they look good

 

well turn the car on and take off the oil cap and if you feel air being push out, that means you have blow by. Which is not good.

 

well i got a new head for it but could the bottom end be messed up to

 

I like to check certain systems together.

I.E. - check everything in the ignition system to make sure your spark is good:
-Check your distributor cap to see if the pickups are still good
-Check the plug wires
-Spark plugs
-Check the timing
-Blah, Blah, Blah

Then start checking all of the components that get fuel to the cylinders... So on and so forth.

Good luck.
