i was wondering if it would be worth while to get a pair of used heads and have them ported with new valves seats guides and springs at a machine shop or just port the ones on the motor or just buy a set already done??? anyone go through this already??? thanks alot

I would only have porting done by a shop that has experience with LS1 heads. Even if you find a local shop with LS1 experience, you are often dollars ahead just buying a set of completed heads. The cost of services (cleaning, porting, valve job, surfacing, assembly) and parts (springs, retainers, locks, seats, seals) are often quite higher than just buying a set of "ready to run" heads.

patriots ive read only good about so far here...so yeah i woald say sounds good

Many of the shops that sponsor this board sell great heads. In my opinion, Patriot is turning out great products. I personally have a pair of their 5.3 stage 2 heads. I also know people that have used heads from Absolute Speed, TEA, and West Coast Cylinder heads with great results.

Ive got some LS1 cores with 918 springs for sale if you need cores. Definetly buy completed heads.

But wouldn't the porter <in general> be making a markup on the parts? I.e., springs, valves, seats, retainers, etc?

Pacific Muscle Cars

Any of the sponsors that sell ported heads aren't going to charge any more mark-up than you will pay for the same parts anywhere else. Actually, the mark-up is probably lower than paying retail for the same parts individually. It's a package deal with competitive pricing.

I don't mind paying a reasonable mark-up on parts. These people are in business to generate profit. Without profit, they wouldn't exist - and without them we would have no support.

I bought a good set of stock ls1 heads, ported myself, and bought all the springs, retainers, valves, valvle job...........My cost where

Stock heads (ebay) $200
Valves (stainless,2.02, 1.60) $300
Pat duals springs $300
Valve Job (MTI) $250
Labor............Priceless!
----------------------------
Total= $1050

A few more Franks and I could bought A complete set already to go. Add a porter on top of that and its a waste of time.
