Great deals.

Good to see your shop offering these options for Z06 owners, because there is certainly a demand for them.

Is your pricing per head? Or is the package price for both/2 heads?
Thanks.

JW7676

Do you have any pics of the completed heads of the LS7 after you do all your magic?

American Heritage

packages are priced as a pair (2 heads per package).

Nice!

Thank you.

Haven't you guys heard? Solid SS exhaust valves are a huge mistake! (vocal inflection indicating sarcasm here).

propain

Mistake? Time will tell. Necessary? Not if you address the guides. Got proof otherwise? No, no you dont.


To the vendor: Good to see someone offering PM guides as an option.

MTPZ06

Just curious...what springs are you guys using in your package deals? Also, any experience with the Ferrea hollow stem valves they developed earlier this year?

American Heritage

We proudly use Brian Tooley Racing Springs in our packages.

Yes we have used the Ferrea Hollow stem valves (F2042P) in a few builds with very good results. We have found our track oriented customers more drawn tword the F2042P valves. We offer both the Ferrea Super Alloy SS exhaust valves (F1597P) and the Ferrea Competition hollow exhaust valves (F2042P) in our packages (same price point to the customer).

What are the flow numbers after the port work, the weight of the valves and do you have a install package deal ( gaskets crank bolt and such)?

American Heritage Performance did my head work, porting of my TB and Intake Manifold, Cam swap and LT Headers... Couldnt be happier with the quality, price and turnaround time!

Great shop!

SS MPSTR

I've never said they were necessary. Proof? How about thousands, if not millions, of solid stainless exhaust valves in high lobe lift, high RPM engines in more applications than not? Seems like they've worked well for a long time. Do you have proof otherwise? No, no you don't.

For the LS7, I have always asserted the machining of the guides were faulty.

SS MPSTR

American Heritage - kudos for offering options to the enthusiasts.

propain

I never said they didn't work. I said they aren't necessary in this application.

BTW sodium filled exhaust valves have been in use with great success since WWII.

Glad were on the same page then. I guess I mistook your trollish post for something else then.

Very nice to see another player in the market...THANK-YOU!

I also echo the comment about it being very nice to see the option of factory PM guides being available.

Cheers, Paul.

Dirty Howie

I have a couple of questions for you, please.
1. Do you have a preference for PM or Bronze guides?
2. Do you use the same BT spring kit for both exhaust valves?
3. What are your guide to stem measurements after completion?
5. What do you think the problem is with the stock cylinder heads?
