Help with 243 Head install on c5
Hello Everyone,
My name is Wes. I am new to LS1's I have a 500whp turbo Stang. But I have been very lucky to have been given a 2001 corvette by my boss as a bonus. Its only has 21k on it.
I love this car and I love the low end snappiness of the LS1. So I recently received a nice set of 243 heads with dual PRC valve springs for some computer and website work I did. I read a lot on here and ready your Sticky’s. So my question is to you. What do I need to install these heads? I know head gaskets is a given. I don’t know if I need rockers and push rods, if I should do normal head bolts or ARP head studs? I also was wondering what Cam I should buy? I have an auto and I don’t want to change out the convertor. This is 98% street car but I would love to make some more power. I love the snappy low end torque it has now so I don’t want to lose that while making as much top end as possible, if I could even gain more low end that would be cool if that makes sense? I have great tuners by me, I will get it tuned afterwards. I wanted your advice on what else I need to do the install, and what Cam to buy. If you sell any of these items, let me know I would buy from you. Just quote me on a whole package with Cam.
Thanks in advance on any help or in-sight.

I don't think it's worth your time to put those heads on unless u put in a cam in there as well. Why go through all that labor, gaskets, bolts, fluids cost to gain 10-12 hp at best. Save up and get a cam in there LG G5x1 and a LS6 manifold + those 243 will be worth it.

well the only fluids he is really gonna waste are antifreeze and oil both of which should always be replaced on a used car when first bought imo... also the heads will be worth more than that a set of ls6 heads on a stock motor are good for 15-20 hp whereas these are stage 2 ported ls6 heads... especially if he got them for nothing then why not. if the op wants to do a cam later on then id replace the lifters that way later on he can just swap the cam he wouldnt even need to touch the heads

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.

Thanks again. Man I can't wait to get these on my vette. One guy at works thinks I could run a low 12, high 11 with these heads and mild cam. He said it wakes the vettes/ls1 up alot. My vette rolls pretty good the way it sits.

consider the cam kit from TSP mentioned above or look at a thunder racing tr224 cam pkg at 114lsa.look at the TSP cam/head install kit.the stock GM head bolts are toque to yield (TTY).you will need a torque angle gauge from snap on to do the stock head bolts ,unless you get ARP head bolts which can be installed with a torque wrench.use the stock rockers .get a mail order tune from Frost.

what you heard is true a mail order tune will make the car drive.... will it make it drive well or get the max effort out of it? Hell no lol. Not that Frost is a bad tuner its just that every car is different when its modded like that sorry to say but your best bet is coughing up the 400 for a dyno tune.

A converter and gear change to 3.42 would wake the car up a bunch. especially if it has the 2.73 in it now.
For cam, stay below 224 intake duration with a stock converter, and keep lobe sep at 114/115. Lift below .600. You have the LS6 intake already. Add headers. With a converter, you can go a little bigger on the cam.
Heads with a small cam only won't get you into the high 11's. That is a big jump from what is probably a mid 13 second car now.
Are you doing the work yourself?
I know because I have an A4 C5.

Since you already have springs all you need is the cam and some pushrods. We sell the cams for 389.99 and the pushrods for 110 a set. If you can you might look to try and have the head milled a little. These motors can run up to 11.5:1 on pump gas, a little extra compression will help with more low end power and throttle response.

I have had a couple people suggest Milling these heads. So I will. How much you suggest I mill them? I have 93 octane here, and I have lots of Torco race gas additive. I use in my turbo car. So I will drop a little of that in there if need be. With whatever milling you suggest what size push rods should I get? I will pick them up and the cam you sell to I think.

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.
