[chevyLUVtoyota]

haw do i know if i have a 22R head or 20R i have 4 heads and thay all look the same to me i was told there was a 20R head in there

Intake ports are round on a 20r and square on a 22r.  You should be able to flip the heads over and see slightly smaller valves on the 20r head too.

  you mean  the intake ports  are round

[kneedownnate]

Yup, fixed it.  Was thinking intake but for some reason typed exhaust.  Maybe cause I just got my new magnaflow today

haha, lets confuse him more and tell him there are 2 types of 22r head..... early and late model, forget which one is which, but one has round exhuast ports and one has pear shaped exhuast ports

[toyman1994]

late model 22r head has the pear shape exhaust ports.

You head looks like this, right?  The head is upside down, but you get the idear.

[chevyLUVtoyota]

yup...

round intake is 20R,  [] is 22R,

pear shaped exhaust  and no combustion chamber = 22RE
