Cylinder Head portings

[ZM_Hamann]

Hi guy's,

i have S50 B32 cylinder head & iam thinking to do 3 angel jobs porting for the cylinder head... any idea about the HP that i can gain from the porting. bear in mind that the engine is stock

1st: there is no such thing as a "3 angel jobs porting"

2nd: 3 (and 5) angle valve grinds do not add HP, they are for getting the valves to seal properly.

3rd: Porting a stock engine's head (without larger valves, breathing parts, and tuning) is not worth the time and money, as you will not gain more than 5-10 HP at the crank on a good day.

4th: Your sig is misleading. Really. Most people who own a decent HP car at least know who to ask such things (the builder if they bought it), because its pretty appearent you didn't build it.
