Synlubes Posted January 30, 2003 Share Posted January 30, 2003 I`ve been told by wise people that you can mess up more than you will gain. Now, if you just go in a clean up some of the casting mess that can`t hurt.(IMO)(just don`t go crazy) If you really want results, pay the price and have a professional do the work. speed/performance = $$$$$$ How fast do you want to go?

Mudge Posted January 30, 2003 Share Posted January 30, 2003 Definately spend time studying before you do it, but with your scrap head it sounds like thats what your doing. Quote Link to comment Share on other sites More sharing options...
speeder Posted January 31, 2003 Share Posted January 31, 2003 I remember a car magazine article listing the 10 best ways to make your car slower. Number 1 was "port your own heads". Quote Link to comment Share on other sites More sharing options...
Mudge Posted January 31, 2003 Share Posted January 31, 2003 IMO, it would require months of study for most people before hand, because many people do work the wrong areas and in the wrong amounts. Ooh, whats this short side radius in the exaust port, I can cut this sucker down and get LOTS of flow! Your best bet is to make a cast of each port, and analyze it, make a cutout, and follow it. Read books before you do this though. Quote Link to comment Share on other sites More sharing options...
David K Posted January 31, 2003 Share Posted January 31, 2003 I say just go in and clean up the casting of rough edges and such. Those little protrusions in the casting can create a whirlwind effect when air is being sucked in or out. Im just for smoothing everything out, dont grind it open any.

Mudge Posted January 31, 2003 Share Posted January 31, 2003 Pretty wise advice, not much real gains unless the casting is piss poor, but its safe. Do NOT polish the intake tract, exaust sure but intake no. Taking material off is where it gets iffy, bowl work is the safest for rookies. Polishing the combustion chamber also a plus, if you can do it without removing material. Quote Link to comment Share on other sites More sharing options...
