[HyperRevved 6313]

Pot until not balance hp won't increase and it'll makan your engine oil as well ... find some experince workshop 2 do it

My engine head was ported & polished by Powerzone for RM1500 (it's not just port&polish but almost a blue-printed engine head), 2 weeks work, no need to leave ur car in workshop, they will take ur old engine head as exchange. Compression ratio maintained. Visit their section for details. Dyno-proven 7% horsepower increase, well, from my dyno experience that is.

No need to play with ur compression ratio until ur engine is heavily modified (eg medium boost turbo or racing camshaft). Changing ur engine's compression ratio requires ur ignition timing to be re-tuned.
