suggestions on heads? whats up guys im new to the site but not new to lt1s and i no the question im bout to ask has prob been posted a million and one times but i couldnt really find anything that i liked so i figured y not ask you guys personally and see what u guys think.....
i got a 94 z28 auto with the gm lt4 hotcam kit-cold air intake-longtubes with x pipe true duals-2500 stall-pcm4less tune-stock mani and throttle body- msd opti-and other lil things here and there....
now my question...i recently burnt a valve in one of my stock heads and figured if i gotta change em why not go aftermarket? now ive been doin lil research here and there and dont know what set to run with my set up for best performance and reliability even no i dont drive her everyday..ive herd i should run advanced induction heads, the gm performance lt4 performance heads edelbrocks or trick flows....
i honestly dont mean to sound like alot of other people with simialr threads but can understand y some would ask.
i was just wondering if someone has a simiular setup like mine that can leave some input on what worked best for them or if any one has suggestions id be more than happy to consider.....like i said im new to the site but not new to mechanics..just never built a lt1 and figured y not ask people whove already done it
thanks for any one who has read and left some advice for me

What goals are you looking for? Lots of ways to answer the question. Then we can move on some ideas.
Either way, ditch the hotcam, the LT4 heads, and the Edelbrocks. It'll be down to AI or LE (most likely).

well ive actually installed quite a few hot cams in various motors and i havent hurd anythin bad from them so for now ill stick wit it since this will just be somewhat of a mild build but thanks..as far as the lt4s the edelbrocks i havent herd too much bout using them but i have herd alot of good bout the A.I. s so im kinda leanin twards them..
as far as my build goes im just doin a mild build for the time being..if i get anywhere from 400-450hp and hit 11s in the 1/4 id be happy and eventually when i find a good tuner here in ny ill eventually just keep upgrading more and more but for now just a nice street car...
once again thanks its greatly appreciated

Running a 2500 stall along with a hotcam will not get you anywhere near 11's with a set of heads unless the car is damn light. The biggest problem I see is the stall, I would get one in the 3200+ range with about a 3600 being very ideal by producing good track times and driving great around town. After that is addressed then I would get a different cam, I'm not putting down the out-of-date old school hot cam (well sorta lol) just saying that your goals will be much easier to obtain with a newer grind or ideally a custom grind. So....I would purchase a heads/cam package from Lloyd Elliott or Advanced Induction etc. etc. and then purchase a stall that will accompany that package well. With that done, you will have upwards of 370-400rwhp and a car capable of 11's. It's all in the setup and half assing one part of it will equate to half assed performance, been there done that myself.
Everyone rags on the Hot Cam and always say it is a waste of money, That's the key, MONEY. They are not paying for the stuff you are, Yes the Hot cam is old technology, but for the price of the entire kit, cam, springs (I know they are weak) 1.6 RR its not a bad deal. The cam and rockers are by crane. Back in the day, I did the Hot cam kit install, Bolt ons, 2800 stall and ran 12.6's all day long in my 95. Of course now I am a little quicker, last time out...138 mph

Well thanx moehorsepower for understandin what I'm tryin to explain and to the rest of u...now they I got a few extra ideas bout the A.I. Heads I'm prob gunna roll wit them for now..now I gotta find a good tuner in my area instead of these mail in tunes..what intake manifolds you guys prefer to use I was thinkin of A.I. Doing one of possibly the edelbrock one?
The hotcam is a decent small cam. But there a lots of other choices that will have the same driveability and mpgs but will produce much better numbers on the track&dyno.
Comp cams xe503 (224/230) is very popular, also similar to a hotcam. I would really get a custom grind and have your heads done by AI/LE. You will tell them what you want and they will spec it out.
With the amount of power you want your stock intake will do fine.

The stock intake is pretty good. You can have AI work your stock one if you want, or you can leave it as it is. Give Phil a call and see what he recommends. He won't try to sell you, he will be straight up and tell you what is money worth spending and what isn't.
425 rwhp (about 520 flywheel) here on a stock intake.
That's the truth. A couple years ago when I was going to go with Ai they recommended I go with their basic cleaning and inlet porting to my stock manifold which was $175. I would have opted for their $375 street/strip port had they recommended that but it was nice to get an honest answer.
