Looking at their .042 heads (which would be a match for my GP 2180), I see both with them and the .041 heads they come with an option for "heavy duty springs". At the revs we use with our aviation applications, using stiffer springs would just wear out the cam lobes.
They also offer "stainless steel valves". There's any number of suppliers for generic stainless steel valves but why not just go with the known best? Manleys. The ones Langford chose for his Corvair conversion are just as good I'm thinking - don't know if they make them for the Type 1 VW though. Another thought, always put new valves in a lathe or grinder and make sure they are true. An old A&P advised me years ago that, even aviation valves from Continental and Lycoming, can't be counted on to be perfectly true. Aircraft mechanics often just presume them to be true, but some are not. This would explain the otherwise inexplicable valve problems some owners experience with a new or newly rebuilt engine. Slightly out of true valves will rotate around the seats (like they're supposed to) and start leaking fairly soon. These MOFO heads look fine. I love the extra cooling. My Great Plains EMPI's from Brazil modified by Steve Bennett have served well over time. Keeping them cool is the name of the game for long-lasting VW engines.
