They make them for themselves... from what I've seen they have a long tube of steel/copper that they "slice" off sections to use for seats.

Honestly I am not sure. I bought them second hand as Schrick 288 but I dont think they are. More likely 300 (in Toda terms). I have spend hours investigating the numbers on them with no result. My CR is 11.3.

those look like "big" cams... they appear to be larger then 8.4mm... (just guessing....) Do you know how close they come to the edge of the bucket cylinder casting??

This is the 272/235 - 9.4mm cam - note it is VERY close, but the bucket has not had to be modified for clearance




Btw.... I assume you are still using the piston/rod combo? Then you don't have to worry about valve interference if you decided to go OS....
