need some head advice please I know this topic has been beaten to death, but after searching quite a bit I cannot find all the definitive answers I need. I would also like some opinions as well...onto my story
This past winter I upgraded my stock ls1 with a torquer v.2 cam and stock ls6 heads with dual springs. I wanted to get them ported but I ran out of money after I got everything I NEEDED for the install. Since then the power has gotten old and I would love some more power and some higher compression.
Ive been looking at ported LS6s, ported 6.0s or possibly ported 5.3s with lower than a 64cc. The problem is that used heads with the specs im looking for dont pop up too often and AFRs, TEAs, and basically any other non stock casting head is out of my price range at the moment. Ive been looking at Patriots because they are definitely more in my range, but Ive heard mixed things.
I have also heard mixed things about ptv clearances with the torquer v.2 and 59cc heads. I would like the highest compression possible without needing to flycut.
So basically what would you do? Get my LS6s ported/milled? What is the turnaround time for that? It is summer and the winters suck up here so I want to have my car as much as possible....
Look for some used Ported/milled heads that are in my price range ~$1300?
Get a set of patriots?
Or scrap the whole idea?
Thanks in advance!

If you have the time I would send the heads off to one of the vendors and get them ported. We charge right at $750 for the porting and $200 if you want larger valves. We would probable mill the heads to a 62cc chamber with the larger valves, and a 61cc chamber with the stock valves just to make sure there is enough clearance. You stand to pick up some solid horsepower doing this so I think its a good idea if power is what you are looking for.

Check build threads in the dyno section. Damian has a few on results from
the Advanced Induction CNC versions of 241 and 243 heads...I think right
around a grand total. This guy really knows efficient airflow as his heads
often pick up 40-50 rwhp with only 15cc intake runner volume increase.
Study all your options and let the pocket book dictate. TSP does nice work
also. I'd stay away from larger valves since you're trying to get more comp.
without PTV clearance issues and you can get about 290 cfm w/stock valves

Heads are key so don't skimp out because of a budget. Trending Topics
