Stay SP or change to TP with twin carbs?

[D@VEY]

Im thinking of getting some twin carbs for my 1600 SP engine would anyone recomend staying with the SP or would i get better mpg and bhp going over to a TP set up?

Twin port heads will be an improvement over a single port engine even with out carbs. Carbs will increase HP and MPG too

To be fair if your SP is running fine with good compression and end float then the extra cost of the heads outway the extra BHP IMO, also the SP heads are less prone to cracking.........deffinatly worth fitting twin carbs tho.........
