Cylinder Head D24 vs D24T

[swital]

Hello
Currently I swap D24T to my Volvo 245 USA 84' Engine from Volvo 940 92', today I took off a cylinder head and on each cylinder are cracks between the valves Before removing the head I measured the pressure and on each was 32 ​​bar, so very good.
I have original cylinder head from my 245 D24. Whether the head of the D24 will be matched to the D24T ? Maybe I can swap valves from d24t head to d24 and it will be working ?

Cracks between the valve seats are considered OK as long as they are less than a certain size. The greenbook gives a spec for maximum acceptable width but generally as long as it is small enough that you can't fit your fingernail in it, the head is considered OK.

Those cracks are very common... I bet that if you pull the head off your D24 there is a good chance you will find it has some cracks too. No big deal if they're within limits -- the motor won't know the difference!

Head of D24 i have already removed and there aren't any cracks My D24 have crank mechanism in bad condition, pressure:
1 - 28, 2 - 19, 3 - 19, 4 - 24, 5 - 22, 6 - 17
So I decided to swap D24T

There are pics of cracks (1-6 cylinders)







What do you think about that and that vertical cracks on 2,3,4,5 cylinders ? How to prevent these cracks aren't expanded ?

they got that motor so hot it wold not turn anymore , maybe afew times is my guess.

Those vertical cracks are fatal. There is a guy on TDIclub who can fix that, but it won't be worth the $ unless you have thousands invested in porting and whatnot.

T has 12 mm head bolts, 11mm for D24. Somebody on here recently got a new one from a company in Spain or Portugal.
