hey guys,
i can soon aqcuire a set of Z06 heads and Z06 cam brand new for about 800 dollars through a friend...

i have a 99 ECSB silverado with the 5.3...

how much of a performance increase would this add???

i currently have just the K&N intake and BORLA exhaust...

also is this a good combo to put on my engine for a decent daily driver HP upgrade????

thanks guys...

If I was you I would reconsider the Z06 heads on a 5.3. The Z06 heads are the same as LQ9 heads but with smaller combustion chambers. I have a book thats all about gen III engines and they put a set of Z06 heads on a 5.3 and lost HP and torque. They recomended the z06 heads on a 5.3 if it had forced induction.

I dont see how you could lose power from a set of ported polished 5.7 heads 2.02/1.57 compaired to a set of stock 5.3 heads? If this is true Im going to cancel my order for my AFR heads. LOL JK

[Hit Man X]

The 2" and larger valve is too large for the 4.8/5.3... you induce valve shrouding as the bore is only 3.78" this decreases velocity and hurts power. AFRs for a 302 Ford only have a 1.9" intake valve that motor has a 4" BORE&#33; Just stick with 5.3 heads on a 5.3.

If you were planing to drop ~&#036;1000 for heads, just pick up a 6.0 motor... better heads already and more cubes.
