Doing head work....which valve springs? Ok....I am talking to a guy who has a set of 99 5.7 heads w/ comp 941s and Lunati Ti Retainers. He will sell me just the heads for $200 or the heads/springs/retainers for $325. The springs/retainers have about 30k miles on them.
I want to use the Thunder Racing 224/224 .561/.561 112 LSA cam.
When I get the heads, I will be having them ported and polished (may have them milled 0.030 for increased compression).
Should I get the springs or just the heads and get new springs/retainers?
Since I am having head work done anyways, should I just get duel valve springs installed? Any idea what the would cost and which springs should I use?

Re: Doing head work....which valve springs? I think duals springs are best.
TR-224 has very aggressive lobes.
Rev has a new kit that doesn't require maching the heads to accept dual's that will allow dual springs to be installed.

Re: Doing head work....which valve springs? Machining heads for dual springs will leave very thin area when heads are ported. If you need dual springs fine but i would avoid this by running 918 springs.I am interested in Rev spring info.
