Stupid Question

[Marcos]

Well ... I am finishing the conversion of a 1.3 Delta to 1.6 SOHC because of the piping had to use 1.3 Head

And my life was never the same .... everything in the damn thing is different from one another :@

Now that I am about to turn de key to start it up .... I realise I forgot one thing (stupid me!) the compression

Knowing that both engines have the same piston diameter and that the 1.6 has 0.1 more of compression.

How bad will it be to keep everything as it is already?
