i just replaced the head on my 1988 s10 pickup 2.5 it runs but like crap. When u give it gas it sputers (in all gears) until i stomp it to the floor then runs good, also when stopped it idles really high. i've put a new fuel pump and filter still does the same exact thing

Did you get the valves set right?
And the correct firing order and timed right?
All vacuum lines on good?

Check the compression and post back readings.

Did you have dist out?
Is the egr valve stuck open?
What is engine vacuum at idle and then at 2500 rpm?
Does it have good hot blue spark to all plugs?

Any dead cylinders or engine miss or just running bad?
