does it make a diffrence in horse power if i port and polish the heads for a 01 grand am gt?

Answer 1

A little -- but can you really feel three HP? It would be easier and lots cheaper to turn off the AC when you need a few extra horses.

Answer 2

.If you know what you are doing it makes a big difference.It will cause the fuel to flow through the heads better and will increase the torque somewhat.To make power on that engine install a K&N air filter.If you can find a program chip that will realy help.And shave the heads at least ,20 thousand`s. 'If you can find a perfomance mass air sensor that will help.By installing a flow Master exaust this will also help.Have your engine DINO tested before doing any of these repairs.That way as you progress with the add ons you will know were you stand
