I don't know if you will find a set of modified vortec heads but here is a kit with everything you need. https://sdparts.com/details/scoggin-...ter/sd8060arpm

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

1100$ so far with shortblock, gaskets, assembled heads but will need a spring swap.

Yes something in that area, I do have a OE roller block though. Im sorting through some now.. Really dont want to spend 300 on it.

Does the milling of the heads effect what pushrod length I require?
I plan on shifting this thing around 5200 on weekends. Is that a problem? friends say no, just wondering if I should install arp rod bolts while the oil pan is off.

Disregard shift point question im going to assume it's okay lol.. I have never owned a 350 so wasent sure about rpm range, at 3200 my 3.8l v6 sounded like a rc car motor.

The cam is a good selection, I like Howards Cams. It is too late to replace rod bolts now. Usually you replace rod bolts then have rods checked and resized when everything is at the machine shop.
