absolutely not.
first of all, you havent given enough information, but i assume your wroking off of the stock pistons.
therefore, that cam will in no way clear the pistons. anything over .512' needs to be notched. see the problem.
we are supposed to have 9:1 compression, but its never over 8.9:1. that cam needs 9.5+...
that cam is also too much lift for those heads.
the alphabet cams are great i dont know what youve heard, and you really cant beat their prices either.
e303 is a good all around cam, b303 will give you better top end a choppier idle.
TF stg 1 is another option.
depending on what year your car is Steeda #18 or #19 cam will work as well.

My top 2 suggestions would be:

TFS Stage 1
Ford B303

Get the TrickFlow Stage 1 cam, it's even cheaper than the stage 2. The Alphabet cams are outdated. They are a single pattern cam. I believe. The TrickFlow is a dual pattern cam. The E-cam does sound good, but so does the TrickFlow stage 1 and it makes good power to 6,000rpm, plus the TrickFlow cams are cheaper than the letter cams. Since you have a mild head and intake system, there is no need to get a custom cam, unless you add a poweradder in the future

lift has nothing to do with PTV!!!AND ALPHABET CAMS ARE OUT DATED..much better choices out there......what we need to know is the entire build you have or intend to evaluate your choices

The duration is what determines the PTV clearance. With those heads the stage 1 would be better though. Whatever you go with be sure to get springs that can deal with the cam.
