Intake valve opens after TDC 10
Please help,
finally after basically rebuilding the cylinder heads with 12 new intake valves I installed the cylinder heads, replaced the timing belt by carefully making sure all the camshafts are aligning at TDC including the crankshaft as well of course.
The manual I am reading talks about "Intake valve opens after TDC 10”, but doesn’t indicate at which cylinder the intake valve opens 10 degree after TDC mark at the crankshaft.
When I checked it was cylinder number 8. Is this correct?
Would somebody who is knowledgable enough please help me figure this out?
Thank you.

Well, I think I figured this out. If TDC is when cylinder 1 is at compression stage top dead center than 360 +10 degree after TDC the intake valves of cylinder number 1 should begin opening and if this is the case then timing should be correct I hope.

If all cam and belt pulley timing marks are correct and at the correct TDC (2 TDC's per cam revs), the precise intake cam timing should be irrelevant...a built-in (preset) relationship between the timing marks and the exact cam lobe position (for best performance and smoothness).
