Perimiter bolt heads for 02 SS?
To introduce, I post under the same name on LS2.com. Someone is interested in selling me a set of:
Stage 1 PORTED perimitor bolt LS-1 HEADS. READY TO INSTALL. THE INTAKE IS FLOWING 250 CFM @ .550 LIFT AND THE EXHAUST IS FLOWING 200 CFM @ .550 THESE HEADS ARE COMPLETE HEADS READY TO BOLT ON.
PERFORMANCE LS1 2.00 INTAKE VALVES
PERFORMANCE LS1 1.55 EXHAUST VALVES
VALVES ARE BACK CUT
CHROME VALVE SEATS
COMPETITION 3 ANGLE VALVE JOB. VALVE SPRINGS (GOOD TO .550 LIFT)
HARDENED RETAINERS
HARDENED LOCKS
HARDENED SEATS
VITON VALVE SEALS
Will these just bolt on to my 02 SS A4? I am unsure as I thought perimiter bolt were not for my year (center bolt). Whats the difference? What will I need? Also will they provide an increase in power?
Lastly, would you recommend a 221/221 cam or 224/224 for a daily driver with this package? the 221 is a Lunati LS1 Camshaft - 221 / 221 .558 / .558 114 LSA 6600 RPM Power Band.
