Ballpark... I'd say you're roughly the same height. If you could shave 2MM... couldn't hurt.Wonder how tall the Heiden set-up is? Maybe I'll just knock that extra 2mm of and start there.
I have the Heiden filters both in the sump and paper element type in the side, i don't suffer oil starvation at all, just keep your oil topped up, there is plenty enough room above the filter, you really do need to leave these uncovered for best results, we run roller bearing cranks and cams so we need high volume low pressure oil feeds for best results, just my tuppence worth.

I have the same arrangement as kevski. Big improvement over standard IMHO and no trouble so far. And don't anticipate any!
