The Big T/A Alumn Head Sale Sure Has Me Thinking

This pic may not be Historcially correct but it is Politically correct :Brow:

I know the Stage 1 SE heads flow within single digits out of the box.....

And my ole M/T Super Scavengers have just about had it......

My combo screams Stg1SE but my heart wants Stg2SE.....

Decisions, Decisions

One thing I do want to say tho is Thanks T/A.

 

I haven't heard about the sale, if someone could fill me in on it please?

Its a sign to join, not only for the heads, but for the other good stuff on sale.

 

are the Stage 2SE extra 4 head bolts holes cast not quite being all the way thru so you have the option to use or not like on the STG 1SE?

This could make my decision for me if they are not.

 

I think the stage 1 heads are the way to go.They flow as good as the 2's, but you don't have to change cams for the best results.

 

Headers too

If you go the Stage 2 route, there are thing like the convertor that need to be changed.
I put a set of stage 2 heads on my Stage 1 combo and the car went from 11.30's, 11.40's to 11.80's. the convertor was border line with the stg1 heads but didn't flash high enough for the stage 2 heads.
Did some research and and went with a 3500-4000 converter and times ended up in the 10.80's with the old stage 1 engine and stage 2 heads.
After building a new engine 3 years ago for the stage 2 heads and another convertor change, I managed to get down to 10.31 before a major malfunction in the engine.
Good luck in your choice
Bill

 

bill excellent comments, the 4 speed conversion will be installed by time of the head swap but i hadnt considered that situation.

this may be the last set of heads i buy, but my current shortblock will not be my last one, so i dont mind leaving a little on the table with my current cam to have room to grow.

 

Can someone post or re-post the out-of-the-box flow numbers for the alum Stage 1s?

I'm being told that they will outflow my mildly? ($1000) ported Stage 2 SEs.

Thanks
Bruce

Try this thread Bruce

 

OK, thanks Ed.
That sets things straight.
Some people need to keep their mouth shut if they don't know what they are talking about.

This is no reference to anyone on this thread.

Have a nice day.

Bruce,

I can only speak for what I have seen with both the Stg 1s and Stg 2 aluminum heads. To me... the intake ports are very close to one another. If my memory is correct the short turn radius in a bit nicer on the Stg 1 compared to the older sets of Stg 2s but that is not a big deal at all.

For Everyone else out there.....

The biggest difference that I see is the exhaust port. Typically 230 cfm on the Stg 1 and 264 on the Stg 2. So... which is better??? Who knows. My opinion is that if your building an all out race engine or N20 engine.... go with the extra exhaust flow of the Stg 2.


Either way guys the prices on these heads makes using the iron heads silly!!!!

Take Care

 

John, I'm not even getting 230 with my Stage 2's! (225 at .500).

I think they need some massaging.....(I don't have the head bolt tubes so there was only so far they could go)

Bruce

 

Bruce,
That couldn't be. Stock stage 1 iron heads are flowing in that area. You must be thinking 330, which requires a little more work than just a good valve job and porting on the SE's.

 

Oh yeah... that is assuming you're talking 28".

 

I'm talking exhaust....

 

Steve, he is talking about the exhaust..

No way an iron head goes more than a few numbers past 200 on the exhaust.

Bruce.. head bolt tubes only needed for the intake..

 

ou:

 

John told me when I dropped my stage 2 SE's off that he would have to be careful so they didn't flow TOO much (on the exhaust side, of course). Isn't 250-260 normal for those?
