best heads for 230/230 .612/.592 111+2 LSA cam? What are the best heads for 230/230 .612/.592 111+2 LSA cam? (Cost effective too!)
I have a '98 Z28 with LT/ORY,SLPLM2,LS6+PPTB/tune/3.23/Vig 3200
Should I go cam only with new suspension, or heads/cam with current stock suspension. The car is also lowered on sportlines, so I know I need LCA's... Thanks for the input!

It sounds like you and I are in a similar situation. The GF has an '00 TA, 6 speed w LT/ORY/exhaust and waiting in the wings an LS6 intake + PPTB. She wants some more power, so I have been looking at the Texas Speed 228R (228/228 .588/.588), since a buddy went with that cam in his Z06 and has great results.
However, since I have to swap lifters anyway, I'd been considering doing heads at the same time to get the most out of the cam. I've been looking at the TSP/PRC stage 2.5 LS6 heads. I figure I'll see some pretty decent results with the 228R, and when she gets bored and wants even more power, we can swap in something bigger like an MS3/MS4, the heads will keep up with those as well.

I think the Stage 2.5 5.3l heads would be a great setup for both of those camshafts. We can do a little extra decking & give a compression bump to compliment the small 220ish cc runners very nicely!

Chris's cam was initialy speced on a 111+4 LSA
He felt uncomfortable with less than .080 intake so he advanced it 2* to get .086
Before advancing he was at .072 IIRC, and that is still more PTV clearance than many common bigger cams out there.
With this cam I would suggest if you are interested in PRCs their 5.3L but with 2.02/1.57 valves (not bigger), unmilled with stock gasket. Ask TSP to set them up to clear a MS3 (They sink the valves a bit increasing PTV)
Another would be Stage 3 Livernois 243 LS6/LS2 casting
With heads, that cam is gonna make some sick power and trq, just make sure you degree the cam to ensure correct valve events as Chris did, look at his results cam only stalled A4.
Who says that 400rwhp on a A4 is tough on cam only? Combo combo

Would it work well with ported 853's?

Why unmilled with a stock gasket? It seems to me you would be leaving alot of compression and or power on the table
I thought when they sunk the valves they didn't flow as well. It seems counter productive. I'm sure that they will still be an improvement but I'm trying to get all I can get. Is it really necessary?
I figured PTV clearence wouldn't be an issue with a low 230's cam. Guess I was wrong on that one.

Dont you mean retarded or is it a 111+6?

You have to compromise here. Most poeple here are running as far as .05x PTV on intake, that is very tight IMO for a street motor.
TSP's 5.3s still advertise 300 cfm with sunken valves. That is plenty for that cam. Ideally YES milling and flycutting with thinner gasket will get a few more ponies out of that combo, but how much is 10rwhp worth to you $$$ ?
That is up to the individual.
BTW it will run on 5.3L with standard height seats on 2.02 valves with stock gasket, but PTV is just tighter. Still many poeple would do it , but my limit is .070 intake for street.

Look at chrs1313 for a thread on his cam only stalled A4
422rwhp/398 rwtq
with heads, add a conservative 30rwhp so should be in the neighbourhood of 450rwhp/420 rwtq +/-
small runner heads would work very well like 220 cc
AFR205 would be my best pick for trq potential

I'm bringing this one back... Does anyone have this setup now?? (230/230 with aftermarket heads) <---- Made famous by Chris1313
If heads were purchased in the future, is it worth it to remove my X1 for the "El Torro" cam? (230/230) lol
Anyone have Predz other cam, the 236/236? aka big brother?? lol

The PRC Stage 2.5 5.3l head can be configured for a bump in compression while keeping clearance in check. That being said the new PRC 215cc castings we're finishing up could set you up with as small as 59cc chambers without dropping p/v!! We hope to have them ready in time for Christmas!!
