Heads for TR 230
Id say TEA Stage 1.5 5.3L heads. I picked up 30rwhp on my first 99 ss with an A4 on a Mustang dyno. That was with the stock tune in the car and a TR224 cam and headers and no other changes except just the heads.

When I get my 6.0L heads, they will be shipped to them for porting and assembly.

This will be great choice
Great price and awesome power.
Freind of mine gained 41rwhp with those heads.

Whoa whoa whoa...Dan, get the cam in first buddy! Then think about heads! I'm getting the PRC 5.3 2.5's, so if you wanna be like me, get those. If you wanna 1 up me like ya did with your cam choice, then get something different like TEA. Wanna talk nitrous now? Or maybe a blower? 
Bringing this back up guys. I have been reading about detonation with these heads if you mill it +.015 ? Is there a safe mill for these heads? If it comes down to tune, I have a great tuner. I have the TR6 plugs in now, I believe the gap is around .45.
Is there a better option?
Looking to get heads in the coming month or two.
Again quick recap, TR230 full bolt on , M6.

Look into the dyno section & spend some time looking at recent results. I think you'll find the PRC heads have great results & make proven power everytime. We stand behind every set of heads we sell, so if you need help with your combo we're always here!
I have dyno sheets from several different heads with camshafts near that size, if you'd like some engine dyno before & after sheets give us a call!

As quoted from a PM I rec'd from Patrick G concerning the PRC heads:
And Predator Z:
The newer version of the PRC heads are excellent. The ones from 2 years ago were not as good. Depends on when they were made. They will work very well with that cam. You can run an .040" gasket without flycutting, but if you mill the heads, P to V clearance will get tight. Patriot Gold springs will be fine, but you'll only want to run the 7.400" pushrods with the thinner gasket. With stock gaskets and unmilled heads, you'll want to run 7.425" pushrods.
Yes those would be perfect,
Mill .015 (3 cc) for a 61 cc chamber (no more)
get them with 2.02/1.57 valves
Pushrods 7.400
Stock gasket
No PTV issue
