Hmmm, couldn't complete that reply with a Samsung Galaxy tablet, which always worked fine on the old forum. Is there a new spot for the edit button?
Continuing on with a PC instead-
Terry has increased cooling fin area from stock by quite a lot, this prevents overheating and reduces hp loss due to heat. Other changes/power enhancements include the suitable large and gas flowed intake ports, probably version number ten or eleven by now, these are currently 38mm for the intake, unless he has changed them again since my heads were cast. The exhaust port is fairly small and D shaped with a raised floor to prevent exhaust gas reversion. This is another trick that drag racers and some Nascar engine builders use to get more power from their engines.
