You can safely mill the heads up to .030 for that cam. You could probably go farther but that is the farthest I would go just to be safe on piston to valve clearance. I don't know of anyone up in that area that does porting but if you get shipping for free we do port 243/799 castings all day. We charge $750 for a cnc port, 5-angle cnc valve job, and milling. As far as pushrod length goes it would really be best to measure once we bring the variable of the milling in there. Most likely it needs to go a tad shorter, but measuring is always best.
First off I wanted to thank you for all your help, it means alot. If you ever need any technology help. Let me know. I do it all.
With that said. If I am not doing a big cam because of my stock stall, and wanting to keep the Lowe end. Will doing the port work be beneficial? I know the milling will, just was wondering if it was overkill to get ported? Also alot of people are pushing me to do headers. I can't afford set of 1k or even $800 headers. But i see used ls6, ls7, even ls9 manifolds cheap. Would any of them bolt up without modification and be worth it? Unless someone is selling long tubes cheap?

you should already have a ls6 intake ,check part numbers or the bottom of the intake to see if it has a flat floor.the port work will add 15+hp.you could port them your self ,practice on some cheap 5.3 heads.comp cam 54-455-11 is a torque cam that should work with a stock vette converter.check the used parts section for some headers and exhaust parts.

Maybe you could find someones take off for cheap. Looks like the fit is good and these are better than C5 manifolds.
The install doesn't look cheap though unless you are a good wrench/fabricator.

Thanks Ron. I was actually just searching to see if anyone has done what I asked. I just asked him how much fab it took to get them on. He got like 25hp out of them. That would be so cool if i could just bolt these is. This way I get a little extra out of my head and cam low budget swap, and not spend a lot more $$.. I see a cheap pair of shorty headers for like $300 in the for sale section are these better than me doing nothing?
If you lived in Oregon, I would give you my Magnaflow Xpipe setup for free.

Oh wow! That would be cool. Could I pay to ship it? And throw you some money for your troubles? I like managflow stuff. I use it on other cars..

Seems on their site they only have long tubes. I am going to try calling them see if they will help.

I would recommend you look into the 224R cam on a 114 LSA. This cam will work well with the stock converter and deliver a very broad powerband. It should have no problem keeping the low end power, if not creating more then you had before. You will at least need new head bolts and gaskets for the head swap. Stock stuff would work just fine for this kind of swap. We offer a full heads/cam bolt and gasket kit for $160 all GM replacement parts.

if you are interested in some c5 z06 exhaust manifolds let me know i have a set i need to get rid of to fund some custom headers...they should bolt right up seeing how your vette is a c5...let me know ill give you a good deal
i dont deserve a vette lol a simply thank you will suffice
but if you got a spare ill take it LOL 
definitly get that car hooked up and drive it like you stole it! i would

I know I am driving everyone nuts, but I just want to make the right choices. My buddy might have a deal for me that I feel I should just do but wanted to ask your professional option. He offered me a Fuddle 3400 stall, and a Z06 3.42 rear for $800. My current rear is a 3.15. You feel it would be enough of a difference for a street car to do this? He said it’s a tight convertor and stalls to about 3k.
