So im finally going to start putting together my turbo motor and would like some help/opinions on what to do with my heads.
The original plan was to push for 800whp using a pt7576
I already have a good idea on the short block, however the heads im a bit confused on and seek some direction..
The original plan was to use 317 heads with the stock valves and a set of ls6 springs.
However, after researching a little bit, i learned ls6 springs are NOT the way to go in a boosted application. The cam will be a 02-04 ls6 cam which shouldnt be too harsh on the valve springs at all, however im looking for a set which isnt to expensive and will meet/exceed my goals. I may even up the turbo size a little bit which really isnt too relative if im getting a good set of springs anyways.
Anyways, the plan now is to use a set of manley stainless steel valves. (not sure on which sizes) and springs i have no idea at all.
I will be having AI put the heads together, id just like a little information on what i should buy before so i can send it off to them so they can install it.
Any information/details of your setup/ knowledge will be great help! And yes, i did search. Its how i found out ls6 springs and stock valves wouldnt cut the cake!

PAC 1218s only like 140 bux

works great with mild cams (under 600lift) and 20+lbs

uses stock valve seals and retainers

I have this exact set up on my stock 317's and have had no issues. I highly recommend it. The stock valves will be fine. Instead of replacing them take that money and put it towards somthing else

scogg and dickey race parts, pace performance, is usually where i buy them

i will be doing a little bit of mild home porting on a set of 317s, and throwing them on my 5.3 and seeing if i can pickup power over my stock 706s shortly

I predict you slow down, make less power but run a higher trap speed.

I think you should port the 706's.
