  8. Step 8

     add these two circles to your sketch

  10. Step 10

      use referance geometry--plane command

      

  11. Step 11

     Only advising that in step 15 it's 10 degrees, not 350. It can be seen at the next part of this tutorial.

     It seems that the parameters are: x is 15 and z is 23. taken from part 29, step 7 spline configuration.
     Don't know the circles dimensions tho, but I'd guess they are 30 and 26.

  Hello Aykut Dana
  I need to model a pushrod overhead valve cylinder head with one intake and one exhaust valve per cylinder. I saw that your cylinder head has 4 valves per cylinder. Will the steps you have for making your cylinder head also work for my cylinder head? Thank you for the help.

  may i ask what the cylinder head exactly is?which part it is in the engine?what is the location relationship between it and the former parts? thanks

     The cylinder head is exactly what it says on the tin. It is what closes the top of the cylinders. It houses the intake and exhaust ports and the spark plug.
