I have a '03 carburetor Dyna stock 88 with HQ-0034 cams. I have some extra parts laying around. So would it be worth the effort to install low mileage '06+ heads and 0.030 head gaskets? Everything is on my shelf to do it.

 

You'll need the late-style flanges for the manifold ...

If it is just sitting on the shelf ready to go, I'd say do it ...

A while back, I posted some info I found online that compares the CFM flow rate of the early TC heads with the late heads ... here's the link ...

Not sure how much 'seat of the pants' difference you'll feel ... I think you'll improve performance ...

... the flow chart on the heads you are dealing with ...

I even have the flanges. I'm thinking the extra compression with the thinner gaskets will wake up the cams.

You need to start your own thread!

 

You are the only one that can answer that question is it worth it to you?

 

It would be if I get more power. That's the point of the thread.

 

I don't know if you can read the url on the top of the graph I posted above ... but, the entire 23-page study can be found at ...
