[QUOTE="pete nice, post: 30071, member: 121"] It would have been a good idea to get the heads flowed while they were off. I know it's a bit late now, but if the engine ever needs to come out again http://www.vwracing.net do a wicked porting job that is tested on a flow bench. They have to use 1300 sp heads for racing & are making 100+ horse with a single 40 carb froma 1300cc engine. The restriction on any VW engine is in the head. You can get some small gains with exhaust, carbs etc, but there is a limit to how much gas you can get in & out. Open this restriction up & then you will see some good results. It's about £150 to have a pair flowed. [/QUOTE]
