Which heads will make the most power on a 350 ci lt1? I'll be buying some heads for my car within the next month but keeping the hotcam for now. I will most likly go with a bigger cam in the future I just want to get the heads out of the way.

AI 200cc ported stock castings with a matching cam.

just like Joe said, stock ported heads from AI or LE will be your best bet. shoot them both and email or call them

Yea I would go AI or LE or maybe even Golen I heard some good stuff about there CNC heads plus they supply brand new cores for you. Unless I found a good set of aftermarket heads in the F/S section for cheap only bad thing about that is most aftermarket heads will lower you compression with stock pistons.

IMO, stay away from Golen.

Using out-of-the-box as-is heads is always a poor choice unlesss you're going forced induction.

For a stock bottom end I would without doubt go for a set of ported stockers from a company with a good reputation. They will be all you need with the limitations the stock bottom end gives you.

Yea not to many people have Golen heads I only know of one person and he hasnt ran them at the track yet.

I would think that the new trick flow heads ported would be the best for a 350 block.

The AI 190's are looking pretty tempting I just wish I cold have got on the group purchase

AFrs with major porting can the best head money can buy, but if you want stick with stock casting with your setup.

yeah pyro, I was about to say, didn't you start the AI Group Purchase thread.

It sucks, you weren't even able to get on that.

Yea that was me lol I should have waited till I had the money

well the way I see it is I could get some trick flow heads that flow about 173 out the box for $1010 w/ no down time or have to worry about fixing the broken exhaust bolts on the stock heads. And if i'm not sattisfied and want more power I could always have these ported and flow 200+

AI/LE stock castings all day. Best bang for the buck.

Now if you dont have a budget some AFR's or TFS heads would be nice but for the price and the fact your on a stock bottom end my vote still stands for the stock castings route.

Fixed (assuming you are talking about the new 21* TrickFlows?)

I plan on going with these for the same reasons he stated, as they are comparable to AI 190's or LE2's out of the box, and then still have room for porting above 300 cfm later.

sepno77

iTrader: (5)

Yep those are the ones i'm talking about. Thanks for the fix.

Let me reiterate:

Using out-of-the-box as-is heads (like the Trick Flows) is always a poor choice unlesss you're going forced induction, or have them ported.

Well unlike the 23* TrickFlows, the 21* versions have CNC'd chambers, which help produce the numbers that they do, AI said in another thread that the chambers don't really need any work. While being cast ports, I'm sure there is some touching up that could be done, but for a stock shortblock engine, they seem to be great as-cast. We have yet to see anyone try these out yet. For me, I don't have any stock castings to start with anymore, so I will have to pay for core/used, then the cost of porting them. Later I plan on building a stroker, and this way, I would already have a set of aftermarket castings to begin with to get some 215+cc, 300+cfm heads. Still undecided personally, unless I see some nice used AI/LE heads for sale priced cheap once I'm ready to buy.

However to the original poster, yes, for the most power on a stock shortblock, you could go LE2, or AI 200's paired with a custom cam would give you the most power.

Well I'm for sure getting the trick flows. They might not flow 275cfm but LE2 arnt exactly 275 either only the AI's are garanteed to flow 275 as they are cnc'd. Ill be getting them w/ my tax's and will post up the #'s once I get it dynotuned. I think they will perform just like the LE2 or prity dam close.
