Topic: 20r/22r head question

[blackxlava]

is there anyway to tell the difference between an early 22r head and a 20r head with removing my intake? i pulled a 20r today for the head, to come and find out i think the hybrid swap was already done to my truck by the previous owner. any casting differences anyone knows about?

thanks guys!

20r head has round intake ports, 22r has square....also the intakes are differant!!

 :willynilly:I know about the intake ports, and sadly the in the truck has an aftermarket intake on it. The only clue I have is under the weber carb there looks to be a water block plate like a 20r would have.

Actually looks like this is the intake I have http://www.offyparts.com/product_info.php/cPath/1_25/products_id/322?osCsid=afad773251213820d9bc1eae22dfd95d guessing I have a 22r head on there now.
