year 2000+ 3100 head same as 3400 lower intake

[fastback4]

Is the year 2000+ 3100 head intake ports the same size as a multi year 3400 lower intake ports.
My salvage yard yet again hands me another set of 1999 3400 heads swearing "these babys are not warped
for sure". Yea they are 0.020 / 0.013 ..So i have this mint year 2000 3400 intake manifold set i would like to use so will a 2000+ set of 3100 heads match the 2000 3400 intake ports?..........Tom

1996-1999 3400 V6 and 00-01 3100 V6

It is interchangeable with the 487 heads (24507487)

Taken from this thread:

I know I saw somewhere on the site where there was a table showing head part numbers for the 3x00's, but I can't find the thread with it in it at the moment. I believe that the 00-01 3100 heads are the same as the 3400 heads.
