From my 400 stroker post I realize I need a better set of heads before I build a short block. I really like all I've heard about the TF 240's, but a close relative of mine has new in box EZ heads and a set of used Indy SR heads that were on a 500" stroker (not sure if any port work has been done to them or not) and I more than likely will be able to buy either set from them.

So price aside if you were to take OOTB TF 240 vs Indy EZ vs Indy SR heads which head would outperform the other?

i can only speak on the sr,s. i had a set of unported sr heads prepped by Dwayne Porter in a 496 combo with a Dwayne spect cam and it ran AWSOME,10:50,s in a 4,129 lb car on pump gas.

Your original post stated a number of critical issues that will limit horsepower. Combined, they will take away a BUNCH of horsepower. I don't see those issues being factored in to the suggestions given in your first post.
That is why I firmly believe you need all the cubes you can build into this motor, plus large port heads, and don't be afraid of a few more rpm. You need to rev to 6600 to 6800 to make your goal, which is equivalent to 9.70 to 9.99 IN GOOD AIR.
My first low deck combo on gas Made enough power to run 9.50s, at 3000 pounds race weight. But I had these advantages. I was 200 pounds lighter, which is at least .2 seconds et, 12.9 compression, another .1, and a roller cam, another .10 to .15, and large port heads. On top of that I was shifting at 6800 because the cam was 283 intake at .050 and .750 lift, with 290 duration and .681 on the exhaust. In short, build what you think is about 75 hp llong for your goal, and if your whole combo is fairly good, you will achieve it.
While that combo I discribed might have had more in it, it was easily repeatable, not a build that used a number of tricks to build the most hp it could. It is tough to make serious hp, so be very conservative on the estimate of what you chose to build.

EZ heads will make plenty of power but they have to be ported. Unported they aren't much better than a stock head.

You are kind of mixing apples and oranges here though. SR heads have a moved exhaust port so that changes things. Both the EZ and the SR head work best when used as max wedge heads which moves the torque peak up and requires a max wedge intake.

Looking at which way you are going to go also requires a look at the total cost per hp. Besides the cost for the heads there are all of the ancillary costs that most people don't think about until they have already purchased the heads. Don't forget to add up the cost of head studs (if different length needed), rocker arms (if different offset is needed), rocker arm hold down studs and spacers(if different one's are needed), valley plate (if needed), manifold change, headers (change may be needed based on exhaust port location), plug wires...
The list gets pretty big depending on what the new head layout requires. Now some of the things you are going to need to change no matter which head you choose, but even then some of those things will be cheaper for one head over the other.

My best recommendation is to find a few builds that meet your needs and do the cost analysis first. You'd be surprised how the numbers fall. For me the choice between the two easily had me going to the trick flows (even with the extra cost to have additional porting done). Both heads were able to get me to the final number I wanted with the trick flows being cheaper overall. And the super bonus is that I didn't have to deal with the Indy poor customer service that was likely to be an issue.

Any chance you could share specifics of the build (head flow, cam, etc.)?

i,ll have to look it all up but i might be able to find it.this was quit a few years ago.

Definitely, weight is a big issue...I have been running a 512 RB for 7 years. Best ET 6.13 and 9.70 on pump gas.....But at 2770lbs. Roller .680 cam with 10.8:1.

I run the EZ-1 heads, and they have been awesome. At your weight, you will want better heads yet.

I have just switched to a 400/512 all the rest the same except light weight crank...Had an issue that has been holding it back. Gone 6.25 so far.

Do you mind sharing what the issue was
