Sup guys. Got some questions. I wanna do a heads/cam install on my tahoe. this is what i'm thinking, but i'd like to get some opinions:
cam with 590 ish lift on intake/exhaust and 360 ish duration on a 112
pushrods
roller rockers
valvesprings
valves
z06 heads (will they fit?)
Thanks.

Not sure if tahoes have a 5.3 of 6.0 if its a 5.3 you will loose power because of compression loss without milling them.

If i'm going to lose HP from z06 heads, what would be a propper head to go with for this truck? Should I keep stock heads and port them?
Thanks,
Ben

Most of the ported 5.3 heads offered ready to go have been worked out to fit the larger bore LS1s and have bigger valves installed. Put these on a small bore 5.3 and you'll end up with shrouded valves which hurts flow.
My suggestion is get a spare set of 5.3 heads and have them ported by one of the sponsors here. Make sure that they know they are going back on a 5.3.
