well first, where is the best place to get my head ported for the buck?

what is the ave. price for a stripe/street port job?

Why would a sohc burn up 2 or 3 MAP sensors in less than 2 weeks?

If i'm running 11.5 to 12 compression, should i be able to run the car on pump gas and still get a good burn on the plugs or should i be using octane booster?

if i should be using booster which is the best i should be use?

thanks guys for the tips and help before hand
