Heads for a 5.3
Hey guys, I want to put togather a head / cam package for my truck.
I want these heads: HERE
But I am told they will ruin my compression. So which heads should I get? Also, Is a head and cam swap really worth the trouble?
Thanks!

Thanks for the replies. So far I have intake and exhaust. I am going to do my own work also.
I got antzy and bought the heads in the auction, I gave him a best offer of $350 for the set and he accepted it, totally unexpected! I plan on spending about $800 in total. Ive spent $400 on the heads, Im thinkin about $200 for the cam, and after that Im going to get a nelson tune.
I have been told that the heads will kil my compression. My question is will it be too low or too high?
Thanks!

LOL, I know I am not capable of installing them myself. I have a buddy who is extremely knowledgable on this subject and has built a few engines. FWIW, what am I looking at to get them porfessionally installed?

You are going to have to mill those heads alot to raise compression
are you going the FI route or staying NA? thats an important question you need to answer before you decide how much to take off the heads. If your staying NA I wouldnt be suprised if you have to take .06 to .09 off those heads to get over 10:1
Oh and buy HP tuners it costs the same as a mailorder and I wish I had done it in the end you'll thank me. If your this far in you'll want to tune the truck yourself, its not as hard as you think just have to take your time and do alot of reading. Im interested to hear how those heads work out. Let us know what you decide.
Oh and on figuring compression the 5.3 pistons are dished I believe the dish is at least 3cc but I could be wrong, so youll want to figure that in.
