Valve spring ?

Do you know of a good single spring that will handle my 560 lift cam its a comp flat hyd 292 magnum 244@.050-560 lift the heads are 68 c8ve-e with 219-173 milodon valves on a 472'' I looked at single springs that rate for way more lift than i have but wondered if you guys have a part# for some singles that i can put on with this cam so i dont have to machine the heads to use the dual springs comp calls for with this cam.

The FRPP #M-6513-A50 - (install 'em at 1.830").

Thanks

Well springs will be here Friday,and along with putting them in the converters going in at the same time also its a hughs 4000 competition, i cant wait to see the diffrence compared to the wornout wrong springs and the tci 11'' breakaway that i cant footbrake over 1500 which gave me a best of 10.57 @128 mph and a 1.48 60'.

yea i always hated were my tci breakaways "flash stall" was like 1800 rpms

you may need some "sissy bars"

Well i never did get to try the new valvesprings i bought that randy recomended because when i got to the 4th one i noticed the upper edge of the notch in the valve stem where the lock locks into was mushroomed out and up a bit( i guess it was ready to drop a valve ? ) Well i pulled the motor out yesterday and pulled the heads today so i can replace the valves and finaly do the victor portmatch on them. What i did find is i probley didnt need to put racegas in it for the last two years cause it dosent have flattops with the 4 eyebrows like i was told instead it has trw 2404 dish pistons so i wonder what my compression has been all this time ? its a 70 dove-a block .060 with the A cast in the driver front side the heads are ported c8ve-e with 2.19-1.73 valves and the #1 piston was .020 in the hole i didnt measure the rest yet. When i did a compression test they were all 193 to 195 psi i thought that would be somewhat high compression maybe i was wrong any ideas? shaved heads maybe or is that a normal psi with that setup using a comp flat hyd 292 cam (244@.050-560 lift) ?

that would suck.more compression would be better but i would'nt cut the heads to get it.

I decided last nite that i'm shipping the heads to the mad porter this week for a RHP tweakin and a custom cam from him as well and if i need to change the pistons for more compression i will.
