Average costs of porting and polishing heads?
Any past experience on the costs associated with this? I know what the cam swap and associated costs are with that, but want to know about doing the heads while I'm at it.
Thanks!
What I plan to do this spring is this:
233/239 cam
double roller timing chain
hardened pushrods
PRC Double valve springs
Morel lifters
Port and polish the heads
ASP pulley's
Have it dynotuned again
Doing 389 rwhp/387rwtq right now, hoping to hit 425 to 450 rwhp and the 400+rwtq. The engine only has about 3000 miles on it right now so I think the oil pump and timing chain will be okay as they are and that the stock LS6 valves wouldbe okay to keep. The idea I have is to create as much usable power across the powerband as possible rather than shoot for peak top end numbers.
This summer will see a 12 bolt with 4:10's and a Ram clutch installed, possibly some lowering springs and related parts.
Thoughts or suggestions anyone?

there is absolutely no reason to pay $1700 for a port job when you can pick up a set of COMPLETE AFR's that'll outperform them and are better castings and no core chare for $2k.btw i don't think you'll have a problem hittin 420+rwhp with what you have planned and i don't think you'll need these ridiculously priced port jobs to do it either.

I just want to have these heads flow as cleanly as possible, this motor already pulls like a mule on viagra and steroids, but there is always room for more. To take full advantage of the mods I listed I thought that a nice port and polish would be helpful. As long as I'm working on a cam change and stuff, I thought what the hell lets do this at the same time.
I know you don't have to remove the heads to do the cam change, just thinking that we could hit the top end of the motor all at once while everything else is apart.
Hell I paid greg good $1000 to REPORT my 238cfm ex. ports to 254 cfm(without a tube on a 3.905bore).You get what you pay for.

riiiiight. thats why TEA heads are found on some of the fastest LSx motors in the country. they're not rediculously overpriced. you generally get what you pay for! he could call FFHP and get damn near the same quality for 1200 maybe? he already has ls6 heads....doesn't have to pay core. why spend more?

To reply to your Q.
I haven't sprayed the car yet with the 395 which is where the exaust ports will shine but on the motor it went a 6.9 with 22degrees of timing.Whats your car run?I'm sure from the looks of you extensive knowlege your car is flying.
take an identical runner volume factory cast and put it against an afr heads, there is no comparison. AFR are 205 cc intake, yet still they are with par to a good stage 2 who run much much larger intake runners.
how many $1700 port jobs have put out this kind of power? https://ls1tech.com/forums/showthrea...ight=afr+heads
does your 395 even do that? i doubt it
and i never claimed spendin more money on heads would net you a better time, since you did make that claim and said you'd spent the $$$ on your heads, i wanted to see what you ran
sr71bbjr, what area you from? maybe we can put this to a real world test instead of just talkin bout it ... your big money heads 395 vs my lil o 346 on some crappy budget heads

remember everyone, unless you have a ton of money in your heads you'll never be fast, just ask magnus and 01-z
