I was just pondering this question. Would a person be better off buying a set of..let say for arguement a set of the 1,359.95 Trickflow heads and picking a cam. Or doing an extensive porting job/cam package like an LE2 or LE3? I think the cost would fall in close to the same. I was just curious. Bottom line I guess witch should put down more power?

Off the top I would say the LE2's would make more power because you lose c/r with the TF's on stock N/A cars.

trick flows are more for boosted or stroker apps... Go with stock castings

you will have the purchase price for thr TFS heads plus the price of porting etc.that comes to 2600.00
gm lt1 heads avg. used price 2-300.00,full portwork,complete valvetrain for 1500.00 its your choice from there

I've got factory castings that were re-valved, ported, and polished and am very happy with the numbers. I probably could have gone a little larger on the valves but went with the machinist recommendations. The numbers below are with a 224/236-112LSA cam on the factory re-worked heads (we did find a problem with the valvetrain which has been corrected so I'm hoping the numbers will be better when I go for my re-tune).

ship them off to either LE or AI....those are two of the best lt1 head porters that frequent these sites...you won't be dissapointed...not ot mention the package includes a cam, so you save another couple hundred buck right there.

I agree. Aftermarket heads have not really outshined the stocks, atleast in as-cast form.

Many very highly respected LT1 headshops prefer 2.0/1.56 valves over the old 2.02/1.6 valves most newbies believe they need.

I run a similar duration cam and using my 12.5 at 107mph run from back in june and my 4250 raceweight comes out to 406rwhp according to every online MPH/weight+HP calculator I could find. AI gets my vote, this was on a mailorder tune too not a dyno tune and through full ehaust etc. it is a daily driver that gets some time at the track not the other way around.

I agree . Port the stockers. Look at my sig with LE2 heads and a baby CC503 in a 4400LB boat.
