Sure will. Use the steel shim 1094 felpro gasket with copper coat on both sides.

Are you carbed? Or do you tune?

Sure have come down in price. Don't know anything about the brand. Personally I'd stick with Brodix, Dart, AFR, or Stock built.

Guess I should lower the price on the ported stockers I just built!

They look similar to the Pro Toplines I've got that I paid $900 for. Then promptly put $550 in after 4000miles cause the guides were shot and there was a crack in them. Then promptly put another couple hundred in them cause the regrind was bad!

Sigh. Could have a nice set of AFRs.

I'll never buy a set of assembled heads again. If I do I'll have a trusted machine shop check them out!

unfortunately i have a tight budget right now and i've had to put some things on hold for the car...but i really could use some better heads and a new exhaust...i know everyone says to save up and get a good set of heads...but my motor so mild right now it really wouldn't be worth a good high end set of heads...plus i later plan to stroke it to a 383...i asked this guy for pictures and casting numbers...so ill see what he says when he txts me back...he says they ran when he took them off but they could be cleaned up and possibly rebuilt...how much you think it would cost to rebuild a stock set of vortecs??

so its looking like i should just buy a new set...if they need to be rebuilt cuz the cost of rebuild is pretty expensive..i could always get a set from scoggin dicky that are already machined for bigger lift..or go for those patriot ones...either way thx for the advice and help

Stock Vortec's will get you to about 380 HP. A buddy of mine bought a 1998 Vortec 350 out of an Escalade with 8K miles, yanked the cam and intake, installed a baby GMPP cam and intake and put down 290 RWHP. He has since added MSD, 3.73 gears, Holley carb and different intake and is pulling high twelves with a 69 Nova. Vortecs are a great bang for the buck if you want to run high twelves. If you had to pay more than 200.00 for a set I would suggest buying a new set that can handle lift over .500.

I beg to differ DLP. The pro heads I've got are a vortec chamber design, but much larger, and I'm only running high 12's.... 109 MPH and 330 RWHP
