    Question Who Ported Heads

    I have a 98 t/a A4 with ls6 intake, lid, Lts ory , 3600 yank, ported tb, cam (232/236 .595 .602) and stock bottom end. I am trying to decide which company has the best cnc ported ls6 243s. I am trying to reach 430 to 450 rwhp without changing over to the fast 90 setup. This is my dd so it will be driven a lot on the street. I know that there's TSP, TEA, Patriot & AI out there but which one has the best hp & tq gains?

    It's very hard to say who has the best when it comes to CNC programs. I would go with TEA personally but that is just me.
    Look at flow numbers to compare but then you have to make sure they tested them the same way as there competitor. For a little more money you can get an aftermarket casting too. Might be a better option.

    Having a small cam is like having a small dick, everytime you go to use it you wish it was bigger

    TEA ports a very nice head. Personally with your HP goals I'd go with an aftermarket casting and start from a better platform from the get go.
    I really like the 11 degree heads from ET. Or a set of AFR's. Trickflow isn't bad but for a 13.5 degree head I would have expected better. The AFR's flow better and they are only a 15 degree head.
