Hey guys. I am going to get a new camshaft for my engine buildup, and I want to know if the springs on my new heads can handle it. I have a set of GT40P heads on their way to me. They have had enlarged (1.54") exhaust valves put in, and are brand new. I have no idea what springs are on them, but if they should be stock, how much lift can they handle? I am going to be using a Trick Flow stage 1 cam, with specs:
Specifications:
* Advertised duration: 275 intake/279 exhaust
* Duration at .050 in. lift: 221 intake/225 exhaust
* Gross valve lift: .499 in. intake/.510 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 2,000 to 5,500
Any help is greatly appreciated.
Thanks!
