I've been thinking about buying a set of 5.3 heads and trying this on my own. I've ported quite a few gen 1 heads and a couple sets of LT1's with good results. What I need to know is where my time is best spent. For istance, gen 1 heads have a poor short side radius and bowls, where LT1's have an excelent short side radius and you can actualy hurt flow if you mess with it. So, what do I need to work on and what do I need to stay away from? I'm not looking to get 300 cfm out of these, maybe 270 or so. I'm also planning on using the stock valves, just having a valve job done and a 30* back cut on the intakes. I think I do this for around $500 bucks, including used 5.3 heads the valve job and 02 LS6 springs (I plan on using the hot cam). Anybody else tried this?

Thanks
Chris

This is getting out of hand, i am considering becoming a sponsor on here and i will need the business, but if i help everybody out than there wont be any needed! I will be happy to consult with any body else on a business level though.Thanks for your inqueries. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

LOL ! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Hey "PRO"fessor FULL that 6 bay shop on route 1 is sounding better every day ! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

First time porting heads.
6.0 heads
Ferrea 2.02 1.55 valves
Heads milled 0.030 yeilding 63.5cc comb. chamber volume.
Intake ports 214cc.
I don't have a flow bench.
Picked up @20 rwhp.
Spend about $900 (parts and machining) and 50 hours. I had standard valve seat grind from local machine shop. Should have sent the heads to TEA or someone for the seat work.
Next time I will spend a little more and go with a sponsor for porting, but hey you never know till you try.

I didn't mess with the short side at all. Maybe I would have picked up more by working that.
I did bowl work, removed bolt boss, streamlined valve guide boss, polished chambers.

386 rwhp, on stock tuning (rev limiter raised to 6.6k), stock MAF, stock pulley, and LS1 intake.

 

Man, I didnt realize I'd start such a mess for you with this post Jeff. lol But like I said, I'm gonna get back with you after christmas cause with those flow numbers and the price you quoted me I'd be stupid not to get them from you. I just wanted to try it to see what I could get out of them. They wont go on a car until I get them flowed and might never go on one. And to all you guys wanting this info, if youve never ported a set of heads b4 plan on ruining a set or two before you get it right. It is not as easy as it sounds. I ruined quite a few before I was satisfied enough to put them on a car. BTW Jeff, have you ever done LT1s? I've got a buddy that might be looking to have his done very soon. I'm in the procces of moving and dont have time to help him out
