Solid roller questions
if you need 3/8 then the heads should be modified to make them fit, if not when you use a smaller pushrod you'll be losing more in deflection then you will be gaining from a solid roller.
Thats when dual taper pushrods are used to lower valve train weight but retain strength.
you should see the AFR's i have massaged is a understatement

We have any of the TFS heads available in solid roller form for around $2800 complete, and we can also get the new 18 bolt version. For your applicatoin I would use the TFS 235 setup for solid roller, Noyzee on here used our slightly bigger TFS 245 on his solid roller 427 setup and picked up 6 MPH over a competitors 225 head, so they work well. The 235 is all you would want on a 408, anything else would just be too big. Also, we've made over 2 hp per cubic inch with .500" lift cams, so .700" is all you would want. Hope this helps.

As Brian said, there heads worked PERFECTLY on my set up.

Almost forgot, our solid roller heads come machined with BIG pushrod holes, and a 3/8" pushrod is fine for .700" lift, we don't go to Manton dual taper until .800" lift.
I was looking into a solid roller as well. When I looked in the comp catalog I found a cam to my liking but was surprised by the spring reccomendation. The cam is an XFI 251/256 .645/.655 113+3. This cam called for comp 921 springs. These things only have 130 on the seat and 400 open if I am remembering correctly. The springs that come on the TEA TFS 235's are 160/450. The guy at comp said they would work fine. I don't know how big of a cam you are going to go with but you might be able to get away with the springs that come on the 235's and save your self some cash.
PS I love my 235's on my 416.

FWIW I'm running a PSI spring thats 220 on the seat and 550 open. It fits in the stock spring pocket. I'm limited to right around .600 lift, but thats fine for what I'm doing.

Alright. I didn't plan on turning much more than 8k due to stock oiling system. Again, thanks for everyone's input, it all helps lol.

i run it to 8200-8400 when im running out the back door. usually running the class i run i run it to 7600-7800 because i need to slow the car down. good luck
I'm not worried about daily driving at all. The car would be a full track car with maybe some weekend driving.
There are lifters that you can run on a solid profile with non-adjustable rockers.
Well I've been talking to a few local people with similar set ups that I would like to run. They are saying I might have a problem lifting the heads for the size shot I want to do (300-400). So now I'm looking at a LSX/454 build. Was looking at getting an LSX Bowtie block and a TSP 454 rotating assembly and possibly a set of World LS7 solid roller ready heads. Don't know too much about LSX set ups though - Do I have to get new sensors/valley cover etc. like I would if I went with an LS2 block as opposed to an LQ9 for a 408 setup or is everything plug and play? Thanks again for everyone's help.

im running trick flow/TEA 245 heads l-19 studs. i have yet to hit the car hard at all but with 100 shot and the new heads i went 9.0 148
i have about 50 passes this season on this set up and have yet to remove a valve cover to adjust the rockers. i checked them one time after the first pass and have not touched them since, so im going to guess me spinning my motor to 8500 rpm for those passes is allot harder on parts then a drive down the road.
if you do an LSX build, contact TEA for a set of 6 bolt trick flow heads (mine are 4 bolt, they didnt have the 6 at the time) run good fel pro mls gaskets, and a set of the l 19 studs to 90 foot pounds and call it a day
