Sure, you could send in your head first and we can perform our program to that unit. You would avoid paying the core charge that way, but then again we could just send you our head and you can send back your too.

The stock SVT casting has lots of room on the topside for every camshaft available from CAT, no need to clearance like you would on a regular Zetec. Not sure what you mean "would it have valve timing"?

Per post #2 the flow testing was performed at 28" of H2O.

We have not performed a test with NOTHING but the head, as quite honestly it would never be used this way, and probably would not be a huge gain - the stock head works OK for an otherwise stock vehicle. We resisted manufacturing a head until good aftermarket cams came out because there wasn't much point without them.

1turbofocus Dyno with nothing changed but the ported head , flow # mean little , dyno of head and cams and other mods would mean little

Dyno with nothing but the ported head ?

And do you have the important info from the rest of the flow test like what it was tested at etc ?

K Dog We resisted offering an SVT based head BECAUSE there were no good aftermarket cams available. Once CAT started offering their billet core units, we got on the project straight away. There just wasnt much reason with only stockers out there, the gains would be good, but possibly not enough for most folks to justify with stock units.

That said, look at the gains at .400" of lift, stock cam territory. Still pretty phenomenal.

Let me know!

Not to nitpick but,
Howsabout listing flow #'s that a stock SVT cam can attain ...

I don't know of many guys willing to stick $3,000 into a cylinder head (cams).
