okay...i seen that someone is perting their TPI base ...and i was thinkin if i can do something without spending money to get some power than why not port mine....okay heres the catsch though...i still have the stock tube runners so will it even give me more power at all or not unless i ahyve the larger tube runners??? also what would i need as far as tools to do this job???? oh,.... and how long am i looking at as afar as time wise...because my car is a daily dirver and i need it for work... thx guys

If you port both, you will gain hp. It will potentially take you 20+ hours. Some first timers can do it faster, depending on ability with power tools and patience.

To do it, you would need a die grinder, dremmel, or anything like that. Next you can purchase kits from places like the ones from standard abrasives, or use sanding discs. I do NOT recommend griding stones unless you are proficient with a grinder, even then it is iffy. The gasket you plan on using for a template. Set it in place with a bolt, loosely, and use a sharpie to trace the ports to mark the stopping point. Then you make it as smooth as possible. Just take you time and you can do it. It should take about 5 to 10 hours per head. That is not counting cleanup previous and post porting, disassembly of the top of the engine and reassembly.

I hope that gives you an idea.

okay...so if the holes you port out curve....than how do u know its gonna be perfecly round and not all messed up??? i would think that you wuld need some type of drill bit thing ...sorta like the bits you would use for making a hole in a door for a handle in a house door or something....with the dremmel tool...would u just go around and around the whole until it gets larger and then move another 1/2 inch in and so on and so on???? and when u say head...are you referring to the cylider head?? i thogth that u just port the intake manifold....

You have to port the intake and the heads for maximum efficiency. You push the sanding disc in the intake as far as you can, very carefully. You can do it how you like start at the top and work in or gently work as much area as you can at once. Just remember, the farther in, less metal usually. You can use a red brillo pad afterwards to kind of smooth it out more.

oh i see...well couldnt you use some emery paper to smooth it all out???? MAYBE SOME REALLY FINE SAND PAPER...like 100 grit or something??? oh... and why does this project take sooooo long to perform???

This is sort of like a more advanced operation than I think you realize. To do it correct, you have to take your time which makes it tedious at best, and a disaster waiting to happen at worst that will only lead to you HAVING to spend money on new parts. There is a reason why good, experienced port workers(heads & intakes, not nautical docks) make big bucks. It is more like an art than a skill, so there is no way to just tell you how to do it right. My inexperienced advice: Tread lightly! Oh yeah, for whatever it is worth, 100 grit is not really fine sand paper either.

yeah....im not too familiar with all this stuff yet really...and i didnt mean to say 100 grit...what i meant to say was 1000 grit.....100 grit is rough....
