7A block and pistons + AAN

Yes, that would be probably the best option.
Though you can use the 7M-GTE and 328i combo. The 7M-GTE pistons will give you 8.5:1 CR and this setup has been tested to 600hp.

I don't want to make frankestein engine )) I could find very easy and cheap AAN block and pistons, so that's better choice for me.

Thank You very much again

Best regards!

I forgot to ask You, what do You mean about dropping CR with 034 gasket?

Thicker gasket will mess up quench, so you might not get as much benefit as you think.

Look at previous page.

Basically dropping CR with a thicker gasket will give you less reward than using proper pistons, even at the same CR.
