Arrow M20 valve adjustment

Hello guys a greeting to everyone.

I hope some one can help me with this issue:

I have a m20 engine in my e34, where i live we have no emmison regulations so i can run my engine with no catalitic converter.

The question lies on the valve clearance for the engine, do the clearences difer if the engine does not have a catalitic converter?? i would guess they do beacause the exhaust valves dont have that much pressure any more. If this is true does some one have an idea of the corect valve clearance for my issue???

The Bentley manual says: 30 hot.
25 cold.

Thanks before hand for your help guys and enjoy your BMWs.

AFAIK the clearance would be the same, though I have not tried that
