I'm picking up Eric's 82US, I know it needs a head gasket (got em)
I'm wondering, I have a set of freshly rebuilt 79 euro heads, and a set of 78 euro cams.. is this a straight swap? any issues I need to be aware of?

TIA
trying to get my act together before it gets here

 

Straight swap. Different cam keys as you know. Make sure you get double springs - IMO, as Porsche went from Single to Dual.

Course, if the head is JUSt rebuilt, you may wish not to take it apart again.

 

I don't want to take them apart, or change the cam keys...
hmmm
these heads and the 82 cams?

 

I don't think there's much difference in the cam profiles until the 'S' engine.

All year cam gears (and gear hubs) fit on either Woodruff or parallel keys, and all camshafts.

78-79 US cams are better than 80-82 US. I have a set of '79s to go into my '81... someday.

 

As Porken explains, YOU SHOULD put the 78/79 cams on the euro heads - I think there should be a good flowing head comming out of that combination - better in relation to the 82 heads at least.

 

so I can swap the heads and cams onto this one without making any other changes?

 

My answer is going to be "Pretty much".

EGR stuff may change, or not.

 

update, spoke to DR about this, he says it's a straight swap
woo hoo... Eric, she's not only gettin new gaskets, she's gettin all new heads!
this should give me a touch more punch, and a new lease on life
