The 5.3 heads are great for a budget N/A or nitrous build. The PRCs are ported and have larger valves and with the shorter runner of the 5.3 they usually have more torque than a 243 head and will also raise the compression which is great for N/A or nitrous.
In your case if you are sure that you are putting a procharger on the car later you would want to shoot for a 8.5-9.0 static compression ratio. Honestly though I would consult a sponser wiht procharger knowlage as to what the optimum compression ratio is.
Your car will run fine with lower compression until you get teh procharger, its just if later you change your mind and dont get the procharger you could have made more power in the beginning by running more compression.

sorry if this jacks the thread but i have a question to ask this since we are on the head thread and dont no if someone on another thread has asked this dont feel like searching hard but i dont really understand compressions so ill ask y does lower compression better for turbo? and y does making higher compression with smaller liter heads make more horespower im srry if that was the stupidest question in the world please dont bash me for it im just curious to know

so let me get this straight, i can go to the junkyard and get some STOCK heads off of a 5.3 silverado and slap them on my ta and this will increase power? how much power we talking here?
