Not sure if you know the value of titanium or inconel exhaust valves but this is actually a good deal.
The new intake valves are like $900 alone. My LSW All Pro's were $4700 with titanium intakes and SS exhaust (from Richard). Just because you find a bare blank on ebay dont think its the same as this set of heads.
Those blanks are about 2000 bucks away from being these heads and they are 1800 to start aren't they. Best of luck in your search.

I'll take that to mean they are out of your budget which is not a problem yea.

i have bought so much parts since i been playing with cars-i was 14 when i bought my first performance part-
i know what most thinks cost and head stuff i know all too well
i am working on a bbc here for a customer with a 10 k top end-still need the carbs
i am working on my 427 with a set of wcch heads which richard did for me plus a intake+ a other intake coming for that
i am playing with a set of allpro heads that i bought a while back which richard is sorting some parts for me-i just got to pay the man when he gives me the bill-
your offer is good but consider your dollar vs the australian dollar at the moment
at the moment-so it might change in the future and we might talk
i have spend a small fortune on the lsx stuff just ask around on here and some vendors might say i am a time waster and others might say he buys a **** load-
i do not mean any harm-
the allpro will cost me what the allpro lsw costed u +freight and custom and then convert it to aus dollars and tell me
Thanks

AH got ya, didnt know what you meant didnt think about the greenback dollar vs Aussie dollar no blood no foul...
I'll look for the conversion rate, but I thought it was free trade and you did not have to pay customs on imports from the US?

Right on, believe me I know the money part of it 
Its scary how fast it adds up. I'm doing the same things as well on over here and it take some serious coin to get what you want. Best of luck and let me know if I can help.
Holy cow just saw the exchange rate !!! Wow I thought we were in trouble when we started giving way to Canada. I had never seen the Canadian dollar worth more than the US until recently. Thats crazy.

If you want you could send them to Bob at All Pro and have him run his CNC program, valve job, and install the guides for right around $1400. That'd put you at $2700 for a 244&250cc intake runner aftermarket casting that....

Verdad Gallardo I'm not sure. I haven't had them flowed. They're a 230cc intake runner as cast. I'm not arguing at all that they are by far superior performance wise to a set of their ported brethren. The benefit to these is you'd only need to have right around $1600 invested in a set of these to have a bad *** aftermarket casting that will still flow extremely well. That's only around three hundred dollars more than a set of ported stock castings.

looks like im going with the afr 225's as i can get a set with .650 springs for 2300 to my house. are the trickflow 225's really gonna give me that much more power for the extra 400+ roller rockers?
im not doing a all out effort but i want some power,just not trying to break the bank too bad,for a vette that will be all street driven i think ill be happy with it
heres what ive decided on:
ported fast 90 combo from ron at vengence
afr 225 heads with stock rocker arms for now
cam gonna have patrick G spec it out
bottom end i guess ill give texas speed a call since they seem to have the best price on a full rotating assembly
opinions?
also on my heads is smaller chambers better to help with flow or just for compression? cause a few sites said milling the heads will alter flow numbers
thanks for the help guys its been a very informative thread!

Good choice on heads. Milling the heads too much will change the flow, however contact Tony at AFR to verify how much. I have the AFR 225's that were originally 72cc, but had them milled to 66cc and touched up by Tony.
see i havent bought pistons yet and dont wanna pass up on the killer deal i can get so i was thinking of going with 72cc chambers and then just have them milled when i get everything else.
sound like the best idea?
Thanks again guys!!

another question i just read this on afr's site Our upgrade spring has higher seat and open pressures (145/390+) to better reduce the risk of valve float in more aggressive applications. AFR also recomends the use of Crane Billet lifters in conjunction with our 8019 spring upgrade.
so ls7 lifters are not a option?

well ive always ran gm mutilayer metal gaskets on both of my motors with 0 issues i kinda wanted to stay with those figure i could just mill them to get the correct compression
tony where do i contact him?
