[sil80dude]

hi guys didnt really find any info on this but i want too know if the sr20de'sexhaust valves are the same as the sr20det? thankyou

I'm pretty sure they are the same. Had a det bend a couple valves and took that head along with a de head to a machine shop and they swapped all the valves over.

They are different. DET exhaust valves are sodium filled, the NA motors are not. The intake valves also have a 6mm stem vs the DET's 7mm stem.

^^^This, intake side are the same size but the exhaust side are larger. So you need DET valves and valve guides. I bought mine from JWT when I re-did my head back in the days.
