Hey everbody. For those keeping score, I've decided on the CompCams XE266HR Xtreme Energy grind. Seems to be a great streetable combo of lift and duration. Another reason I like the cam is because the lift is under 0.560", the max lift on the Windsor Jr. heads. The rest of the combo is this: March ram air, 75mm Pro-M MAF, 24lb/hr injectors, 65mm TB, Cobra intake, BBK full lengths & h-pipe, BBK regulator, gauge, & 190lph pump, and 2500 stall. The 3.73's, underdrives, shift kit, and K&N are already installed.
Now for the question: are the Windsor Jr.'s the best bang-for-the-buck heads I can get? I don't want to go with 2.02's unless they're Trick Flows, but even then I'm still concerned about compression. Windsor Jr.'s are the
only ones that have 58cc chambers. Looking through several mags and charts, the flow numbers are okay to compare as well, but I'm wondering about port velocity now, too. You can have a HUGE port volume, but unless the velocity is high enough (what FI is designed for), it's a dead charge. This is where I'm questioning the Jr.'s. Seems more and more they're designed for carbed engines, so now I'm head hunting again. Any probs for ne1 using these?
I'd like something I can get good
volumetric efficiency with, still retain good compression, possibly get P/V clearance with the XE266HR (0.544/0.555 valve lift), and use stock style pedestal mount 1.6 roller rockers if possible. Edelbrock Performer 5.0's a possibility? Trick flows really that great? I need heads capable of supporting 350+ HP, but still good for a daily driver. Which heads are gonna do this for me??? Thanks for any & all help!
