Can you get these castings bare and if so how much?

They have a custom valve so we won't be selling them bare. I'm very reluctant to sell any of our aftermarket casting heads without valves. The valves are a very important part of the whole cylinder head package. The PRC LS3 heads use longer valve so we can get the spring pocket up away from the port.

Perfect time for a dyno comparison....

Are they 6 bolt heads?

They have 6 bolt ears.

Install height completely depends on the spring configuration your running. I have a set here @ 1.850", but with a few retainer tweaks & lock changes I'm sure you could get 1.900".

I'm getting ready to order the heads next week just need to know what gaskets do I use with these heads for a Bore x Stroke (in): 4.06 x 3.62 (103.25 x 92 mm)?

I've been holding off buying heads for my 10 SS for a while.
Id like to see some chasis dyno numbers from those heads and your 231/236 cam.

I've been getting the link for these heads last week. But when I would click them or *add to cart*......... they would say..... "no longer available" Glad to see them availble now.

So what is the deal with your small bore LS7 heads? I've seen them posted saying they are ready for shipment , but no listing at the TSP website. I am interested in flow data and options. Flow data seems to be asked for alot. Just saying.

Jimbo mine should be at the house soon. (LS7s) I ordered them on 21 September, just waiting waiting. Here's the flow #s though

Jimbo1367

Thanks! So what are you putting them on? Any previous dyno numbers with OLD heads?

thanks,
Jim
