Will Carrera Heads Fit on 930 Cylinders?

[RarlyL8]

I'm putting together a fitment fixture for 1.625" turbo headers and need to use Carrera heads for the port size. The Carrera cylinders will not plug into the 930 block as expected so I need to use 930 cylinders.
Will the Carrera heads plug into the 930 cylinders?
Does anyone have a set of junk 930 cylinders I can purchase?
Thanks -

Yes, they will bolt right on. If you notice the intake height is different on the 3.2 heads. They need the insulator so you will need to either stack the intake or buy aluminum housings for the injectors the length to compensate for the short intake.
I dont understand why the cylinders wont plug in, theyre suposed to slip in. I built 930 engine on a 3.0 case and it all worked.

Thanks for the reply.
The bore of the 3.2L cylinders I have is larger than the bore on the 3.3L turbo block. This has me sctratching my head as well. I don't want to waste a lot of time on this so will find a set of junk 930 cylinders somewhere and plug them in. If the Carrera heads fit on the 930 cylinders all should work OK.

The turbo cylinder walls are thinner but the case bore for the cylinders is the same.

It sounds to me like you have 100mm cylinders.
3.2 Carrera cylinders (95mm) and 3.3 Turbo cylinders have the same spigot diameter.
3.0 95mm cylinders as well as 3.2 Carrera, 3.3 turbo and 3.2 short stroke/ 3.4 98mm all have 103+ mm spigots.
100 3.5 cylinders have 105+ spigots.
100 3.6 and street 3.8 cylinders have 107+mm spigots.
Don't hold me to exact numbers as they are from memory and these days, who knows?

100mm cylinders, that sounds like the problem.
So Carrera cylinders do fit.
Now to find some junk cylinders ...
Thank you!
