Now i apologise for being a tad slow but i need a basic understanding of whats to gain in moving transfer ports ( lifting them ) i visit the odd forum or two and read a lot but i'm sure that some of the more knowledgeable and experianced hands will set me straight as regards our Mac engines ... and what can be done
PS some examples of various port timings and there need to be moved or what advantage is gained in doing so needs to be explained to me .... i'm just a poor old country boy so please have mercy on me.
