B660 is the intake cam and B61P is the n/a Miata exhaust cam

Once again a question then. The intake cam is OK as is? But to us the turbo, the exhaust cam should be changed. Correct?
The car runs good, just lacks power.
Thanks for yourk reply.

All of the intake cams are the same, all B660.
I searched on the forum here, it appears the stock Capri exhaust cam is also marked B660.

What exhaust cam is in the car?

If it is down on power it could be something else too, related to the work they did. Head replacement is fairly invasive.
Could be the timing belt timing, poorly adjusted throttle cable, pressure leak in the intake piping, etc.

The head was replaced with a Miata head and the cams were to be changed.
The ones they removed look rather clean is one reason that lead to suspicion.
The belts were changed as well. The car does run well and dad was so happy to have it back while we still had a couple of nice days to drive.
I had hoped the numbers on the cams would have indicated for sure that the turbo cams were removed from the old head and installed into the new head. (Turbo vs. non Turbo).

Well hey, if all else fails, I still have my parts capri with the n a head still on it. It's been sitting without the valve cover, but I bet it would clean up nice. And I come down to the cities once a month for drill, from Duluth.
