Default do i have a bad head?

ok i have no compresion in 1,2,3. the block is rebuilt with 0 mils on it, as for the head i got it from some one and they said it was rebuilt, but this makes me thing that he was lieing, the head is a y8, i all so would like to know how hard is it to do the valve job on it, cuz im not going to pay 200+ to get that **** done....

Its very possible the head has bent valves, thats why u r not getting any compression.It is also possible that the valve lash is so tight that it isnt allowing the valves to close back all the way

if its bent valves just put new valves in it. U can loosen all the valve adjusment screws then try doing another compression test to rule out the tight valves also

Get a manual and it will tell u. If u dont even know what tools u need then u polly arent mechanically inclined to do it anyways. Take it to a machine shop with the new valbves and b done with it.
