No need to apologize I should be thanking you for the long post! Looks like ill be putting this thing together and calling it good for now. hope its not a dog. Moving on to find vortec heads.. I would go the 416s route but finding 40 extra hours for porting would probably take me a quarter year.

I'm not sure what style of head gasket came in the set I bought. Almost positive it wont be the right one though.

The hot cam would work well, but you will have to have vortec heads modified for the lift and use the correct valve springs.

Always!! Well you got your options open a comp magnum 270h or 280h will make plenty of power. A similar sized xe cam may run a little smoother and be more street able. But it does not look like you are forced to run a really big cam. In the same manor i wouldnt go too small. Some ppl will swear by certain cams but they all got a purpose. Not sure what type of heads you will end up with but they should be matched up best you can. There are many different vortech heads and a bunch of ways to port them. Best bet is to see how much head you get before ordering the cam. Weak heads get a little smaller cam big flowing heads you can go bigger and make some good numbers.

The cam edelbrock uses in its kit is pretty hot and it makes about 400 hp. So you figure your cam choice should be pretty close the that one for 350 or 400 in your motor. The kit also came with alum heads so you can see quickly with stock heads its going to be in the 350-375 range even with a large sized cam. You can look at edelbrocks site to see the numbers on the performer rpm cam. I am only using this as an example because the publish numbers. Many ppl run good numbers with less but that is what they are willing to publish with there power pak combo. You really need to get your heads and measure everything and run the numbers and see what the dcr will actually be with the cam and heads to make sure its going to be dead on. I think the 270h is a safe choice but may be a little big. Im sure others will have better dual pattern cam choice. I try to avoid going, this is the cam for you buy this! Because its hard to say what is best for someone else. And sometimes the perfect cam runs like mush. Because of something you didnt plan on bad pistons or crap heads that look awesome but dont flow. I can tell you i have put cars on the dyno and quickly decided the cam i got sucks and its got to go. So im being a little gun shy telling you exactly what to get. without heads anything i say is a wag a wild *** guess.

Sorry looks like ive answered my own question and it does.. The price is def right but ill keep looking at similar priced cams. The hunt continues for vortecs around 400... There is plenty of stock rebuilt vortecs for that price but none with the upgrades i would need. The hunt continues!

Okay I Just bought some vortecs about 5 minutes ago Hopefully a quick spring swap and they will be ready to roll... Not sure about intake manifold ports matching since the heads have been milled but im sure it will be solved one way or the other...

The only 12 bolt intakes that even come close to matching the Vortec ports are called raised port (RP) intakes. RP intakes are a single plane design w/large runners and are made primarily just for racing. Using such an intake on a street engine- unless it was a carefully built semi or full race deal- will not be a good idea.

Other 12 bolt intakes lack enough material above the ports to enlarge them to match a Vortec head and still have enough material to reliably seal to an intake gasket unless the intake is welded first. The port sides may also be mismatched.

For a strong performance build I would recommend the Edelbrock RPM intake made for the Vortec heads, p/n 7116.

Too late now, but for not much more you could have bought the Bow Tie Vortecs.

thought the bowtie vortecs were over 1200 for the pair?
I know the heads are drilled for early intake patterns but i DO plan on using a VORTEC STYLE intake.
I was wondering if the milling of the heads down to 59cc will effect how the intake botls up? Ive read that if done properly It should not.

It will change the port alignment and how close the intake ends are to the block. Look them over when you get them to see if the intake flange has been milled to correct for the deck milling.

A guess is that about 0.035"-0.040" was removed to get that volume. But the amount removed also depends on what the volume was when they were original- often the volume is larger than what's published. You might even ask the seller how much was removed and if the intake flange was corrected.

For more info, see: Milling cylinder heads

EDIT- Bow Ties are more, my mistake.
Good luck
