wat gains wud i get?

 

gains would be minimal unless you are really going all out.
if you are not gong all out , at least ensure that your ports are lined up and make your own gaskets that fit properly.
When i was still using my dellorto 40 dhla's , i had ported the intake manifold into the head so the intake ports were almost the same size as the carbs - i gained response low down and stop cavitating with my T34 in mid range cruising

 

depends on who does the porting ive seen heads flow worse than standard

a good ported head should give +30 bhp on a standard engine the more boost you use the higher the gains

 

depends on wat the engine spec is already, with the right cam and set up could gain up to 40-50bhp

 

It's far too hard to generalise, but by porting the head, you will lose peak torque, so unless you have a turbo that can blow hard enough, the engine will lose it's punchy feel.

Depends on how you drive it.

I made 290lb/ft on a standard head at 250bhp, it was a gearbox breaker. Once the head was ported, peak torque dropped to 250lb/ft, but it felt stronger through the rev-range. If you don't have at least a stage 3 turbo, don't bother IMO.

 

personally, i think C is talking balls

 

i saw 25hp on mine when it was done,

std cam, port matched,flowed,and big valves...

much more tourque aswell,
