I have bought from these folks a couple of times. And will be buying a set of these in the next couple of months. Great prices, great machine work, and a good warranty to boot! If I remember correctly they're out of Texas.

Re: Heads for a 350 chevy

now that's a great deal. i spent a little more than that getting my stock heads rebuilt after having trouble with two sets of vortecs.

Re: Heads for a 350 chevy

Not a bad deal for 700 bucks complete. The intake runner is on the smaller side being only 185cc. If your not looking to make any huge power numbers than these heads are probably the best deal out there. Probably support 450hp NA. (referring to the patriot vortecs)

These heads are tapped for the old andnew type intake manifold, also perimeter v/c or centerbolt v/c.
Be weary of the dual bolt pattern though. We put a set of those on a '91 Formula and the intake ports were taller than the stock TPI intake casting. Meaning the with intake setting on it, you could see about .030" of the top of the intake port. We had to order a Vortec TPI base to make it work. You could get away with a Wieand Team G or a Victor Jr that have bigger ports and raised casting, but don't think you can put a stock intake or even a Edelbrock Performer on there and go. I will not work. The intake ports are about .170" taller than a normal stock SBC port.

Otherwise, they are wonderful heads. That 'bird is one the stoutest N/A TPI cars you'll see.

Re: Heads for a 350 chevy

I also assume i could use my stock intake and edelbrock elite valve covers?

Also what roller rockers and rods would go good with this?

Those are the 305 heads (416 and 434 castings) that have had the chambers enlarged and bigger valves added. We've run them before, and they run stronger than a stock old 76cc truck, but they still are have a small intake runner and are limited. They are OK for pepping up a stock engine, but don't expect big HP out of them. We flowbenched a set one time, they and maxed out about 210 cfm at 25" H20 at .500 lift. They are OK for $300 though.

Re: Heads for a 350 chevy

Well im not going to be making like a drag car or anything but i dont want to be limited if those arent good enough. If im going to spend 500 might as well spend more now and not later

Any other suggestions besides these vortecs ?

http://paceperformance.com/index.asp...D&ProdID=73011

I was thinking i might buy it individually so i can put different roller rockers ect. Thats probably at the top of my budget

Most are probally made with centerbolt. If you go to a local pick and pull yard and fing a set. Have the machine shop check them and drill and tap the rocker studs.

I had no idea the intake ports were that high on the pp vortecs, good call.

Allyou ever wanted to know about Vortec's, These really are the best value for the money, IMO, you can find intakes on EBAY or RACINGJUNK.COM, PURPOSEBUILT.ORG, CRAIGSLIST etc...

Pay attention to the casting #'s to avoid !!!!!!! These might be why there have been some naysayers in the post.

Re: Heads for a 350 chevy

How much horsepower are you looking for? I reworked my own set of the 416 heads, and enlarged the whole chamber instead of just unshrouding the valves. And mine were only 1.94/1.50. I also port matched, and enlarged the intake runners to 170cc. They were on about a 350 horse 350, the truck would run a high 14 sec 1/4 mile.

Click the link, and they had a save $50 on a $200 order, so you'd get the vortecs for closer to $500 for the set and new, just get the self aligning rockers, and a vortec specific intake, and if you want to use the valve covers you have, they make an adapter to go from center bolt to perimeter so you can use them on the Vortec heads, trust me 30+hp over any of these stock heads mentioned here and better performance than even the Dart's SR's etc, etc under or at .500 lift, after that the Dart's etc out perform the Vortecs, but over .500 lift is not really a daily driven street motor either, plus 6,000+ rpm and that is the only way/time any other head out does the vortecs!!

GET THEM!!

Re: Heads for a 350 chevy

I think if it was me, I would find a good used set,get them rebuilt by a good shop, and spend the money you save on an intake..

I found a set of 1993 LT1 Aluminum heads locally for sale for $175.00/pair...I try to rebuild before I buy new if possible...but I like looking for parts as much as buying them.

I'd stay away from LT1's if you are not running them on a LT1. They are reverse flow cooling heads, and require welding up some of the coolant passages, drilling new ones where there isn't and resurfacing the head. Then you will need a LT1 specific intake. Not really worth it IMHO and the cost of the machine work would be nearly as much as a decent set of Vortecs, and you would have many more intake choices. The Vortecs flow much better as well. The only really advantage the LT1 head has is that they are aluminum.
