best cam for TEA 5.3 and A4 I am planning on getting these heads and am curious what would be the best cam. All things being equal(converter,bolt-ons,etc.)Car is daily driven.

Re: best cam for TEA 5.3 and A4 I'm using TEA 5.3 liter heads milled .010 with a comp XER 228/228 .581/.581 on 112. I hope it works well. I'll find out next spring <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: best cam for TEA 5.3 and A4 Best cam will depend on your goals and other supporting bolt on's. What stall are you planning to run? Gear?
I like Comp Cams 216/220 as a nice daily driver cam. It isn't hard on the valve springs and can make nice power etc. This cam will work best with tuning etc as all cams work best with tuning.
For a daily driver a TR-220 would also be a nice cam.
The Comp Cams 220/220 XE-R could work well but will be harder on valve springs.
Good luck

My TEA heads were supposed to only be decked .005 for clean up. With a smaller 224/224 .581 XE-R cam with 4 degrees advance, my P to V on intake side is very tight. My cam will have to be retarded at least one degree to get acceptable P to V on the intake side. I think my heads were probably milled .015 instead of being decked .005 for clean up. It's not a problem because my installer is degreeing in the cam and check P to V to make sure it's right. However, with a bigger 228 cam I would really want to check very carefully to avoid future problems.

Re: best cam for TEA 5.3 and A4 My cam only has 2 degress ground in. People are running 230/224 cam with 5.3 heads milled .010 with no issues. How much were your heads milled ?? I've seen people using the 224/224 cam with heads milled .050 with no issues.

I should have had no issue. However, my installer Jesse at SRP checks everything before it goes into the car. He checked just to be safe and for my set up it's a good thing he did.
My heads were decked .005 for clean up only per Brent at TEA. However, my P to V appears to be way tight for the heads to have actually have only been decked .005 for clean up as I was told. For all I know, the cores were decked somewhere else etc before TEA got them.
I'm not bashing TEA, just suggesting a check of P to V might not be a bad idea. Checking P to V is a good idea on any install with ALL heads and cam packages. With a big cam check this! This isn't intended to upset anyone, just be safe and check is all I'm saying. Jesse, will degree the cam in to make sure everything is as it should be for acceptable P to V clearance. I would have liked to have more P to V clearance but that's not how this worked out for me on my set up. That's the risk I took when I decided to do heads and cam for my car.
I like TEA and expect good results. However, I will deal directly with Brian at TEA instead of with an intermediary. Later, if I do a big bore engine, TEA will be conidered along with LPE and a few other choice LS1 head porters. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
My TEA heads will work fine with my 224 XE-R cam, it's just the set up is tighter than I wanted. My cam has to be retarded a degree or two for the desired safety margin. I can't upgrade to a bigger cam like a 230/224 later without redoing heads. I will change my dual springs out to be safe after about 25,000 miles instead of 50,000 like I'd planned. Tight clearances with a fatigued spring can equal P to V contact. Next springs will be Cryo treated etc so maybe I can get longer life. It's nothing I can't deal with because I'm lucky and live near Charlotte, North Carolina - the heart of NASCAR country. I have a good friend Jesse that's a professional (NASCAR, BUSCH, NHRA) racing engine builder by day doing my install side on the side at his personal shop.

Re: best cam for TEA 5.3 and A4 I like the idea of cryoaging valvesprings and valves. I can attest to the part strengthening and hardening that this procedure provides.Machine work should be done prior to Cryo genics to keep from dulling tooling. FWIW I run a Comp custom grind PRE XE and XER lobes that has these specs: .585"/.585"lift, 224*/224* at .050" 276*/276* at .006" on a 112*lsa that i have advanced 6* with 5.7 heads milled .035" and i turn 66oo rpm with no ptv issues, i dont know what the clearance is but it must be enough! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
