what ur input on the 317 heads vs 243 heads?

 

do the 243 heads not 317..

 

that what im thinking. I want to figure out my compression ration with these. Im starting to think i might go with these. Do they flow better than 317s. I could do a search but im to tires now.

 

243's and 317's flow just about the same, but the 243's will bump up your compression alittle...

 

the heads decision goes up to what pistons you have and what compression ratio you want. i got a set of flat top mahle pistons SUPER CHEAP so i went ahead and got them, i figured i could run my ported 5.3 heads and high compression or my ported 6.0 heads and run mild compression... best of either world, depending on the mood i'm in the day i finally assemble it.

 

I studied on this for months, and came up with my setup. I'm doing the same thing, only I wanted to go with the tvs1900. I'm waiting to figure out a few things, before I get the blower, 1 HPTuners, and 2 whether the 1900 is right for me. I called and talked to everyone that has been suggested,and more. I figured out that lopey cam isn't really right for a blower, or turbo, but on the other hand my tc is only 1800 stall, so that throws my figures out of wack. Richard at WCCH, and Allen at Nelson Performance were the most help on this subject for me.
