ok so at the end of last summer i put on a set of 241 stock ported and polished heads.. i also put in a cam 224/224 .581 .. i was not sure what kinda springs and retainers where on the heads so i purchased a new set of springs and titanium retainers.. i just popped off the valve cover and took a look at what i had.. i compared them with the original stock heads off the car.. and it looks like my p&p'd heads have titanium retainers but am not sure.. i got some pics of them compared with the stockers.. can anyone tell me if they are titanium and what kinda springs i have.. they have a white stripe on em and appear to me to be beehive.. any help is greatly appreciated(stockers on left)

They "might" be PSI 1511's. You would need some measurements to confirm. You could also contact "Yeahdoug" by PM, who works for PAC, and see if he recognizes them as one of PAC's products.

Retainers are titanium, but don't know about the springs.

Vettenuts,
PSI1511's have a micropolished finish that makes them look semi-chrome, so I don't think these are 1511's.

Yeahdoug

As far as I know, we have never striped white.

Aaron,

My Dart PSI 1511's were nitrided and had a dull appearance. I know the set we installed last summer were shiny. I guess I was wondering if the installer might have picked up one of the Dart sets that went up for sale when the heads first came out as there were a number of sets for sale when guys swapped them out for duals. However, I don't remember a white stripe on mine.

Here are my PSI 1511's. Note that the retainers shouldn't be used for comparison as Dart has their own retainers made and they differ from the titanium retainers sold by CV Products, who sells PSI springs.

I installed a set of PSI 1511's on a friends car last summer, they were the "ML" version and shiny as Aaron mentions above. The retainers that I remember look very much like the ones you have in your photo. You might want to contact CV Products and see if they recognize them. Also, if you have a spring checker you may be able to take some force measurements and with the wire diameter and spring diameter nail it down.

I e-mailed my friend to see if he has any photo's of his retainers/springs installed.

Is the wire ovate or round?

PSI I believe doesnt make a ml and non ml
There is only one 1511 and Dart uses it,trick titanium makes theire retainers.

The PSI springs on my Dart's pre-date the "ML" version. I believe the current surface treatment was introduced later. I have one of the first production set of heads though. Below is the PSI table I copied when I bought the heads, but you are correct that if you look today you will not find the non-"ML" version.

so it appears that the retainers are titanium.. so one would think that there should be decent springs in there.. at least to .600 lift.. so in all ur opinions.. should i leave em, or put the new ones in??

They are an excellent spring/retainer...
Leave them alone,good to .625 at a install height of 1.80@120
