I am looking at getting heads for my lt1 but am not sure which ones to get.

My mods are:

383 stroker with eagle rotating assembly
12:1 compression
comp cams cam with 510/510 lift and 220/230 duration
Comp cams 1.6 roller rockers
manley valve springs
58mm TB
30lb injectors
ceramic coated headers
CAI

Any info would help. I am looking for a good amount of power and decent price.
Thanks

i would run a cam with more lift an i would get the new profiler sbc head and have it converted to reverse cooliong..the decks are think and good and the head flows 294 at .600,298 at 700 lift and 304 at .800 lift..

there around 1250$ for a set..

heres a thread on them

Definite x2 on the larger cam. Strokers need lots of lift and duration to fill the larger cylinders, and that cam won't even come close to cutting it.

I think ported stock castings will work well for your build (they worked for me). Check out www.advancedinduction.com or www.elliotsportworks.com.

i agree stockers ported by a good porter will do the trick..i always like to over head my engines a tad just incase down the road i say hey let me toss a plate on her..

How do you know you have 12:1 compression if you don't have heads yet?

i suggest the new trick flow LT1 21* heads ported by AI. i think they are like $2500 CNC'd from AI. oh, and get a custom cam from AI matched for the AI CNC'd LT1 TFS 21* heads above better than the current cam you have.

if you're set on running a cam that small, get some le2s or ai 190cc. no sense in spending big bucks if you're going to limit the combo like that.

do not waste your money on trick flow junk or ai **** and porting..ill be flat out real with you..get the heads i posted an have them converted..a shop should be able to do it for 200$ extra..

in the world of sbc 23 degree heads trick flow is on the bottom of the list..

you want to know the best heads for as cast an price goes like this

dart 215cc 1500$,brodix 215cc 1500$,rhs 215 1400$,afr 210cc 1550$,profiler 210cc 1250$'s

Now if you want the ulitimate heads and have 3k-6k to blow the run down gos like this

brodix -11s or -10x worked heavy and welded up,rhs heads are nasty also talk to tony at bes,all pro 245s worked over and cfe's 23 degree heads..

in order i know of engines n/a with single carbs from 841hp,860hp,89xhp and around 950hp.

no one i know of has ran a set of extreamly worked over profilers yet in a top n/a class like nmca pro stock or ram racings 10.5 or dr class..

Dude, you are a certifiable ******* retard. I hope you know that. I get appointed sick of people spouting **** they read on the net when they gave never DONE ANYTHING themselves. Just shut the **** up.

OP, call AI, Lloyd Elliott, etc and talk to them. You'll get a lot better info than asking someone on a forum fit advice. I would scrap that cam and get one specd to go with the heads you choose. LE3, AI 200 ate some PROVEN combos. This Brodix this, and trickflow 21 degree that, that everyone is preaching are much less PROVEN and more spendy. Stick with what works.

That's all that needs to be said. Nothing else.

I was thinking the same thing.

wtf?

This has to be the dumbest advice on heads he could possibly have gotten.

1. AI and porting your heads = ****? You've just lost all credibility with that statement.

2. who the **** cares what the best as cast heads are? All he should care about is which heads make the most power for what he wants to spend and the setup he is looking for, which for LT1 street cars almost always means ported heads.

3. Did he say his engine was a carb? No.

4. Did he say he was looking to make 950hp with these heads? No.

How bout a full weight, all motor, pump gas lt1 that traps 141 mph. It runs those bottom of the heap trick flows you talk about.

I've got a set of 245rr's.. 370cfm on a 4.030 bore.... how much you wanna pay?

In all reality, the avg joe isn't gonna pay the coin req'd to play w/ these castings.. They're pricey.. They will however blow away any LT1 casting.. i'm quite sure of it.. just not for the 1700 h/c price points L/E,Ai,etc have..

I feel sorry for anyone coming to this site thinking responeses are accurate.

This site used to be great, then it lost many knowledgeable posters to LS and it became decent. Now the responses are usually marginal at best and often are simply wrong.

Why post if you haven't done what you are talking about? Many things can be done, but if you haven't DONE it, you shouldn't post. If you want to post and haven't done it then simply say I think it is possible or in my opinion.

There are soo many incorrect threads on here now the search is close to useless, and if you need help askng a question here is at best a crap shoot.

Before you post ask youself am I adding to the information or just increasing my post count?

This site isn't about people it is about cars and helping people keeping LTX's alive

CAM is small for a 383. What are your goals street, strip, etc. How much money do you have to spend. I have had LE heads and they performed well making ~400 RWHP for track time on a 350 LT1 wih a 306 cam, and if it were me I would also look at AI.

What you intend to use the car for will help decide but money often determines the decision

Good luck

Edit I typo'd hp car weighed 3600 race weight and went 7.65 in 1/8
