Wanting to run this cam with these heads over my X1. I here great things concerning TEA heads and FMS cams. My heads are milled only .005 for cleanup. Will it fit?, 112 or 114, How much power gain?, And how much tuning over X1 or will it be close? I made 413rwhp with current set up through locked verter and 399rwhp unlocked. Thanks.

 

i have TEA stage 2s with the larger exhaust valve than the stage 1.5's mine are milled .016 im using stock MLS head gaskets and i run the F13 230 232 595 585 113 no problems still using the 987s springs with 15K on them running it to 6800 as you can see below

 

are yours 5.3s or 5.7 heads?

 

using 5.3s. They flowed 306 & 267 @ .600. Good #s BTW.

 

Kurtomac, are your heads 5.3's too?
