Cylinder Head 24-1003015-g (24-1003015-Г) Опции

I want to ask you. I bought the car with engine nr. 21A*443271* and cylinder head nr. 24-1003015-G. I read somewhere, that the both (engine and head) are intended for a compression ratio 6,7 (ei. for 76 octane petrol). I do not know, if the head has been modified for high octane petrol, but I suppose no.
So, what is my questions: If the head has been no modified yet, is it really intended for 76 oct. petrol? What type of spark plugs should I use for this head? If I want to use 95 oct. petrol, is the height, which I need to remove, 3,5 mm? And can I use the same spark plugs after modifiing?
Of course, before cutting the head, I want to ask service station for measuring the compression ration.

Thank you for your reply. I first measure the head. Then I will read everything about cutting the head. I saw that there is a lot of information on this forum about the cutting the head.

In order to cut the head, you need to give it to specialists and say how much you need to cut, and they already know how to do it. As for the candles, yes, I was wrong, those candles that I indicated are long candles, they were on my VAZ-2108, I was wrong when I looked at the packaging from them. Candles BRISK NR17YC well fit you
