Yes you can do this, just need to get the valve seat re cut.

Tnx.My friend told me to put head from 1.9 engine on 2.0.He said that 1.9 camshaft is better,it has a bigger valve lift,and i want to put exhaust and inlet valve from 2.4 in 1.9.if i add this part, do you think the valve will hit the pistons and damage(break) the valve?

There is a thread open which has a link to the different cam specs. The 1.9 and 2.4 cams are virtually identical with the lift from the 2.0 being 0.5mm less.

I fitted 45mm valves into a 2.0 head and ran with a 234 Kent cam with no interferance problems. If the head/block have been skimmed then you may get problems. Also you may find that with the 45 mm valve the piston cut outs are not the correct radius so could just touch.

Advice is do a mock build with a used head gasket and combo of cam/head fastened in place with plasticine on the top of the piston. Turn the engine over by hand, dis assemble and check where the valve marks are. If the engine gets to a point and sticks you have interferance issues and will need the piston pockets enlarging.

Have a read through some of the threads posted on here especially Bob's head porting ones.
