Default poll: keep my current heads or sell them for something else

ok i recently bought a set of stage 2+ gtp heads, the heads are ported 241's. well anyway i have been debating on whether or not i should sell them for some aftermarket castings or if i should possibly try to find a place that could rework them and possibly make them into some really sweet heads for a lil cheaper then aftermarket heads. what would you guys do? Also does anyone know someone that has done really good portwork on 241's??

As far as I am concerned, GM castings are GM castings...not to say you cannot make them work...you most certainly can....but after all of that work on them, you could just throw a set of aftermarket heads on there and do just as well, if not better...

It all comes down to how much $$$ you have....honestly

Hope this helps (BTW, I have PRC 5.3's, they are VERY nice for the $, but I am stepping up to an aftermarket casting next)

:EDIT:

Plus you are only working with 241's.....at least work on the 243s.....241's are useless AFAIC....

i wouldn't say that 241's are useless by any means..i know of quite a few people that have put out well over 450hp with ported 241's and decent sized cams..even the guy who sold me mine was putting out over 460 to the wheels on a mustang dyno and another guy i know was running low 11's at 122mph with the same heads i have and a 228 cam..i would say that those results would be just as good as aftermarket heads or any other ported factory castings. Not ot mention one of the fastest stock cubed LS1's in the world is running ported 241's

I would just go for the aftermarket castings now. I have patriot performance 5.3l heads now and i were to do it all over again id go with an afr or tfs head. Id probably swap them now but im too lazy to pull the heads and do all the work again. Save yourself the hassle of not being completely satisfied and do it right the first time.

actually if i could find a good deal on some used AFR's i would buy them in a second but truthfully for the same price of AFR's i could get my heads reworked and still have lots of money left over...if i was gonna spend 2 grand on heads i would actually buy some cartek stage 3 or 4 LS6 heads

BS, our 241s put down well over 470 to the wheels sans the TC on our A4. 440rwhp with the TC. We did 5rwhp more than a similar car with ETP 215s, EWP, and a MS4 on the exact same dyno with the same tuner for about 1/3rd the cost.

It depends on how you use them.

If you are in a position to get aftermarket castings then so be it, I would not mind a set of TFS 215s myself for my Vette!

I port and polish the same heads all day everyday ranging from 853 heads 241 heads and 243 heads my 241 heads produce very good resultes on the dyno. We do stage 1,2,3 and add anything that you would like the 241 heads have a lot of meat that can be removed very safley and bigger = Better. Call me at 858-829-5107 and I will read you a couple of flow charts sheets that we have done in the last 3 months.

A buddy used to run high 11's @ 120mph with GTP heads and 226 cam. They make power plain and simple.

exactly...that is why i am going to keep them, however i have heard that over the past couple of years they haven't been as good as they were a few years back and thats why i am gonna get them flowbenched. If they don't flow what they claim i guess i may send them back to GTP to get some additional port work or to someone else, either way it will be cheaper then buying aftermarket heads
