I was just curious but I've been hearing that I shouldn't waste my time porting(any kind of port) a 13b because of the 6th port or something like that ....can anyone elaborate on this.

Exactly, what are your plans for this engine??

this a BIG 6port street port





you should get a nice power gain with porting like this

well I was planning to do a bridgeport but I'm also looking at SWAPPING to a tubo engine so right now I'm looking at all the pros and cons and while I love turbos I am also intruiged by raw NA power........and rough Idles mean nothing to me.

so let me know what you suggest on the NA side of the house.

pros of N/A reliability, lower maintenance, lots of high rpm power, no turbo lag



cons: very little torque, have to rev car high to go fast, very loud exhaust note
