im doing the pi swap on my 96 gt im having fox lake do a stage 2 port job and i have a Pro Products typhoon upper and lower intake plus 75 mm throttle body, bbk cold air kit,underdrive pullies, bbk long tubes, bbk xpipe, and flowmasters and 4.10s i need to know what cams i should get for the new heads and if i should do anything else that you guys have had success with like maf, injectors, n2o i plan on dyno tunning also one more q what have u guys done with the egr valve is it a good idea to take it out or should i leave it on

I went with compcams stage 2's for the npi heads, and they pull all the way up to the 6500 revlimiter that tim @ mph set up. Plus they have a decent lope to them. I kept the stock maf and injectors and still made 271hp with non ported heads and stock pi intake.

im thinking on changeing my npi heads for the pi heads pretty soon but i also want to change the stock cam that they come with, i was wondering if you guys know if will have to change the spring on the new pi heads or will it work fine like that ? thanks i appreciate ur help

The stock springs work with some comp's with no ptv clearance problems but I know for sure you will be finewith a set of VT stage 1's everything stock will be ok.

do you know where can i find those at, and you say vt stage 1 ? im sorry but i dont know what that means is that the brand ...

I've got npi cams in my pi heads. I didn't know how far I could go with the npi pistons so I went with the lower lift cam. Yes Vtengines.com sells stage one cams that don't require new valve springs but stage 2's do, aswell as new dished pistons if you use the staeg 2 cams with 550 lift thats why I went with the 495 lift npi cams.
