I've got 2 sets of our ported DE heads up for sale.. They are the same Stage 2 heads that I run on my VQ swapped Spec V's, and work great with anything up to a C8 cam. I have several cars in the 11's - low 12's with these heads and a good set of cams.



Stage 2 VQ heads-

Numbers with Standard bore fixture, on Superflow 600 flow bench:

STOCK intake port flow @ .475" lift- 268cfm @ 28" of water
PORTED intake port flow @ .475" lift- 302cfm @ 28" of water

STOCK exhaust port flow @ .475" lift- 163cfm @ 28" of water
PORTED exhaust port flow @ .475" lift- 190cfm @ 28" of water

Here's a few pics..

On a big bore (3.950"), these heads pick up even greater numbers due to valve de-shrouding.

They feature:

Stage 2 port work (short side radius, bowl area, port reshaping in the throat area to increase runner size, removal of casting flash, combustion chamber clean up)
SERDI 5 angle valve job
JWT springs with shims (good up to .475" lift)
New valve stem seals
Decks cleaned/checked for straightness (and skim-cut if necessary)
Heads hot tanked/cleaned, and assembled

With these heads, and C8 cams, you can bolt-on 50hp to your DE engine without touching the bottom end.

I'll take 1550.00 per set of heads, with NO core charge. If you want a set of cams to go with them, I can do any set of JWT VQ35DE cams for 995.00 per set to go with the heads.

Here's a good pic, showing the work that I do in the chamber and short side radius area..



This is a chamber/port on a QR25DE head, but it gives you an idea. The port on the right is stock, and shows all of the areas that must be cleaned up. The port on the left shows the changes made, plus the port flow lowered in the throat area, to give a straight shot at the backside of the valves.
