lol thanks
quick and easy question...
quick and easy question... I have a chance to grab some 317 heads from a member here.. im starting to do some research, and my future plans are a 370 + boost. Not looking for 1000 hp here, just looking for a bad *** set up. Will ported 317's hold their own?? looking for anywhere from 600-700 rwhp. Top end will be ported 317s & 90/90. Any info would be appreciated!
Thanks!
Thanks!
theres a guy on another board making some real serious hp with 317 heads, a lot of boost-the heads had a lot of work, so far no problems
my understanding is the L92 heads have a weaker deck

Have you never seen an ls motor under 800whp push mater? I have, including one of my own. I'm sure it has and can be done, but I think its more challenging than a simple "Use GM MLS and 12pt ARPs". If it were that easy, you wouldn't see so many threads with people having issues.
we'll i dont know what to tell you.I cant speak for how other people do things,but i can tell you this.I have on more than 1 occasion built 800rwhp turbo engines with 317 heads using arp head studs and mls gaskets and not had any problems with lifting the heads.Hell we made 625 rwhp on a bone stock ls6,factory heads bolts and all.Guy has been driving it for a good while now with no problems.I guess maybe i'm just lucky.

I think it makes a big deal how much the car is leaned on too. I race the F&%# out of my car all summer long on 100* nights on slicks. A lotta load and a lotta heat.

I haven't seen so many threads with people having issues at 800rwhp. I can't speak for your setup, but tuning has a large amount to do with it up top. We can't pull timing by gear or MPH (or over time even) like aftermarket EMS's, so what works on the dyno and what what works on the street when making pulls through 2-3 gears is not the same as what will work when you put 4 gears together (3 if A4s/thxxx's) for a full pull from a stop. It's easy to pick them up and push water at the top end of the track if the timing isn't exactly where it needs to be.
yeah,i guess i should elaborate a little.Making 800 rwhp without pushing the heads off is hard to do.You have to have the correct size turbo and a perfect tune to make it last.most people have too small of a turbo and they have to run the **** out of it to make the hp #,way out of the turbo's effecientcy range-which is really hard on the engine

keep em' coming.. $250 for bare 317 heads is A LOT cheaper then a $2,300 head..
Im hoping i can find some LOW mile 317s, and get them ported by someone to have a decent boost head.

Do you have to pull the engine out completely to install the studs & heads on an F-body? I cant see any other way but wanted to ask just incase theres an easier way.
