if i was at say 10:1 the head gasket approach would be fine. at 11:1 to get down to say 9:1 the gasket would be so thick to change the cc of the head
that my rocker geometry would be binding. the cr is not the only factor in gas
requirement. cly head flow, camshaft, and stroke play a significant role in this also. the limited driving i do with the car wouldn't make me change the build
so i don't have to add a half quart of lead. remembering to keep the quarts in the trunk is the hard part.
