GI.SS Posted July 30, 2013 Report Share Posted July 30, 2013 How would ptv be any different than a standard ls2? Same flat top pistons same dimensions for heads. Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted July 31, 2013 Report Share Posted July 31, 2013 Factory casting is a 71cc, 799 is a 65 cc. Tea would only deck my heads to 67, or at least that is what they told me. The only thing I'm not sure of is if the 799 and 317 share the same deck to valve height when they are stock. If they do, even though the 799 has a smaller chamber, any decking on the 317 would then have less ptv. Do you have any articles or links that say the valves are the same depth from the deck to the shallowist point of the valve edge Sent from my SAMSUNG-SGH-I747 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Akslowroller Posted July 31, 2013 Report Share Posted July 31, 2013 I'm tuned in. I keep leaning toward a NA build myself. Can't wait to see the final results Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
GI.SS Posted July 31, 2013 Report Share Posted July 31, 2013 They share the same valve to deck height as the 243 casting. Ill find the link. But with dimensions they are exact to the 243. What makes the two bare castings different is the way they were actually cast. When assembled the valves and and springs were obviously different. Two different company's got the contracts. I have personally seen a vette with one 243 and one 799 head.it confused me which lead me to look it up. I'm on my phone right now but when I get a couple minutes ill post the link.
