Found this segment on K&N air filteration by David Vizard in his video on how to improve Series A Mini Cooper engines from back in the 1970's. Relevant to all engines.

Thank you , interesting clip , the presenter is one “curious George” plus he got luxury hair !

Been watching more of this viddy. Lots of interesting topics that should be applicable to many engines. A discussion of how to maximize intake low valve lift flow and why this is more effective than high valve lift flow optimization for power. Compression ratios, octane ratings, Intake valve seat angle considerations and manifold porting are also discussed.

This guy is still going strong these days (and so is that hair!)...here's an excellent brain dump on valve spring design....linear vs beehive vs taper/conicals:
