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.

I don't think you'd have any ptv issues with the MS3. I had that cam in a LS2 I had with stock pistons and 7.400 Puhrods and didn't have any issues.
Even if, for some reason, you did have a ptv issue it could be made up with the length of the pushrod.

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

What intake would compliment this setup? Considering picking up a FAST intake soon if either will work well with this setup compared to the LS6 intake.
