PRC 2.5 243 Heads & TSP 220R Cam
Purchased a set of PRC 2.5 243 Heads that have been milled .020 along with a TSP 220R cam. Was wondering how well this combo will work together? Got a great deal on the heads and cam and couldn't pass it up. Will be selling my NEW MS3 cam and the stock heads from my 2001 Z06 when I install this stuff so I really wont have anything in them at all after they sell.
Mods:
ARH 1 7/8 LT & O/R Pipe
Modded Ti Exhaust
Breathless Performance Vortex Intake
Car will be a supercharged car down the road just wanted to go ahead and get the headers when I found a used set cheap to pick up.
Any info is greatly appreciated.

What did you pay? A 220R? I would ditch that small cam.... I would run something like the 228R or V2/V3. Unless your going for a stock type cam with just a little more umph

I'd use the heads and then put the MS3 in there. Of course definitely check your PTV Clearance. You will have to do a lil more work ie check PTV and possibly cut valve reliefs, but the reward will be SOOO much more.

How can the PR length fix the PTV clearance issue?
I'm running a small cam 220/224 111, FTI grind and l really like it. Lots of power down low and a mean sounding idle.

you mite make 385-390 rwhp.figure out your static compression ratio and what your dynamic compression is.maybe that cam will create too much dynamic compression for a super charger.

i had a 224/224 in my stock ls1 and it made 600rwhp to 5krpm......but i was running ethanol. if you have a chance to run e-85 do that and dont worry about it. you'll make badass power.

dude if youre on a tight budget take the prc heads and 220 cam and use it, itll be very driveable and have only a mild idle, youll freaking love it i guarantee it. You'll have power everyone and the milled heads will up your torque bigtime. You dont need flycut pistons and a 23x/24x cam with stock compression AT ALL.

i agree here, i have a 220/224 112 (278/282) .575/.575 cam and i was very surprised at this small cam. Sounds very good, people mistake it for a larger sized cam all the time. I used my stock 241 heads at first but then decided to mill them 30 thou , 3 angle grind and blend the bowls. Not much really but the difference it made without even porting them or touching the exhaust side was definately noticable - so the PRC heads should be great!

Thanks for the info guys it is greatly appreciated! I will give TSP a call and pick there brains also. I knew you guys would know more about this than I would.
I figured it was worth it to pick it up for the price.

Do you think a D1SC will have a detrimental effect on the dynamic compression
