Higher compression would benefit more, but no, no head modification except pushrods and springs.
AFR (Tony) used a 224/228 XE-R 114+1 (IIRC) with milled AFR 205's and managed 480+ rwhp. (To give you an idea of the potential of a cam that size with proper compression and supporting mods)

Are there any current good 224 grinds that someone can recommend?
I don't want to replace my valve springs anywhere near 15K miles. I assume that I will need to purchase the COMP 921's to accomplish this task.
Anyone have a good recommendation for this duration cam?

Otherwise it is not a matter of miles, it is a matter of maintenance and once every 10K, one should measure seat pressures and install heights on cam setups.
You don't want to mess with that then get a milder cam.

Speed shop still insists on a 224/228 with a 114 LSA. Is this going to be a really loud setup with QTP's, catted Y, and a magnaflow catback?
Seems odd that one would have to do constant maintenace on a cam if you put in $500 dual coil springs? How often does the seat pressure change?

You monitor the springs so you do not break one if they fall out of spec and cost you a motor. It is part of internal mods. Springs do not have a life span, some last less and some last longer. I has to do with a lot of variables such as which lobes used, method of driving, oil used, etc....
There will be some valvetrain increase, but can be diminished with proper p-rod length. At least 7.425 size with XE/XE-R lobes in cam only setup.
With your setup, this is the cam I would put in for good street power
224/220, .581/.588 113+0 LSA
Peak at 6300 rpm, mega trq down low to midrange, shifts 6600 rpm, - 4* overlap so will still pass emission and have a nice cam sound.

In AZ you dont have a sniffer test for OBD2 vehicles, just a plug in. So the cam they are recommending is a good one for a DD.

That is a very good recommendation.
They are still offering to order a custom grind 224/228 w/ 114 LSA and to install with pushrods and Comp 921 springs.
What would be the advantage of a smaller lift cam than what is recommended above? Would you bump up the LSA to 116 with a possible advancement?

It will make power later in the range.
My reverse split will make power earlier and more trq across the board.
Mine is a XE-R lobe. It is a variation of the Stealth II cam, with an earlier powerband to be use with less compression than the Stealth required (I owned one).
It is no longuer really Stealth but not an overlap monster either, yet still it will pass even Cali smog with proper tune.
Reverse are known for their trq producing manners, Look at X1 from MTI and TR 227 and TR230 for exemple.

For the cam you recommened what do you think the powerrange will look like? Talking idle on up, or around 2K which is what the shop said the 224/228 has. Looking keep the car happy in the 1000-5500 RPM range.

224/228, 114 LSA 110 ICL
42 >IVC> 6200 rpm peak
52>EVO> trq will come on later and won't be as good in low rpms
8.08 DCR
224/228, 114 LSA 112 ICL
44>IVC> 6300 peak
50>EVO> trq still later and a tad better in midrange, will carry a little better
7.95DCR
224/220 113 LSA 113 ICL
45 IVC> 6300 peak
43>EVO> loads of trq low-midrange
8.02DCR
As you can see the 224/220 113+0 still has same range DCR but will produce more trq and earlier in the range due to its 43* EVO, (VS) 50* and 52* on the 224/228. 114+2/114+4 respectively.
Range of the 224/220 will be like 1800>6600 +/-
42 >IVC> 6200 rpm peak
52>EVO> trq will come on later and won't be as good in low rpms

WOW! Great info, wasn't expecting that. Thank you very much. Now do you have a recommendation for an existing cam, or do you beleive that a custom is the only way to get this type of grind?

Great info. Have you seen a table or chart that shows a range of IVC and EVO numbers betwen and their effect on the powerband? Or the limits you would want to keep them between? Also I read somewhere that it's better to keep each number closer to each other like that last cam you speced opposed to the first. Any truth to that?
Thanks
Thanks
