The world cup cam is using these springs. You also have to remember that these heads have the NaK filled valves. They are almost as light as a Ti valve. So you can get away with a lighter spring.

But it never hurts to have a better spring.

You can but these heads bare from SDPC (as I did) and have them milled to your own specs and assembled with your choice of valves/springs. Had it all set up just the way I wanted for a hair over $2000, and no core charge. I think an awesome deal by any measure. Will have dyno info with a B1 in a couple weeks.

Whoops sorry.

On a side note, Hey Josh where are those flow numbers???

Josh @ LPE

Here you go guys! Sorry it took so long, been selling lots of those S/C and turbo packages!! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> While the low-lift numbers are about the same, the advantage really starts to show in the mid-to high lift #'s. Also, we use the stock-size exhaust valve, so the #'s will be the same.

.200 159
.300 228
.400 278
.450 296
.500 309
.550 314
.600 314

I'm not sure if 296 @ .450 lift or 309 at .500 lift is more impressive! That's amazing!

Outstanding numbers! the mid lift numbers are very impressive! However, could you also post the intake flow numbers with the LS6 intake attached for these heads?

If possible it would also be very nice to see the exhaust numbers with a 6 inch pipe attached.

Josh @ LPE

Blackbird-
The only heads that we flow with the intake and exhaust tube in place are the GM heads. All of our #'s are with no tube or intake. We also have a Stage 4 that nobody really knows about!! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Yes, I said Stage 4 (!!!), that will really knock your socks off!!
