Is aftermaket heads worth going to vs. stock worked
Was wondering if aftermarket heads are worth the hp gains over stock worked heads like 241s or 243s, what would be the hp difference in the trickflow 215s vs. 241 or 243s port and polished. would the trickflow 215s be worth the $2000 over cheaper stock worked heads.

It depends on your goals.

One persons definition of worth it may not be another's. Personally I like the idea of a basic proven budget build with a little shot of spray. Still probably cheaper than some high end HCI combo, but would make a lot more power

What he said. Spending money on aftermarket heads would be on the bottom of the list on anything other than a race engine, and even then a good set of worked over stock heads can take you pretty far.

Who do you plan in sending the heads to? If you're dropping ~$400 for the 243's and another $1,000-1,100 to get them worked, that's an expensive set of 243's...I would prefer an aftermarket casting. I went with my 243's bc I knew someone who could port them for about $300 so I only have $700 in my heads. If you're paying retail all around I would start off with a better foundation in aftermarket casts.

Is that a friend? If anybody at a shop is charging $400 retail for ported/polished heads..you should probably run. I only went through my guy bc he had experience with multiple successful LS builds.

Whats your goals? Id most certainly say some worked over 241s or 243s. AI and TEA are both top notch. As for paying $400 for 243s and another grand for CNC work, its still a bargain. No upgraded rockers needed with stock castings. AI has some awesome package deals as well, my .02

goal is to make over 400 rwhp. getting a custom speced cam also. the car will be street/strip and weekend driver. the work to the heads would cost me around $400 to the guy i was going to take them to but not sure if he has experience in ls motors. i think i will try AI and TEA with the 243s seems they would make the most hp for the money

Stock castings are good to a point. What makes AFR TFS et. The best is they use their own casting, thicker deck, better valve angles, better spark plug positioning and the chambers runners etc etc. Where stock castings cant compete is the low and mid lift airflow. They STOMP gm castings by far and are worth the money if it isnt an object. The better choice depends on your goals and budget.
If you want great performance, room to grow in the future, and an aftermarket casting I highly suggest you check out these:
Trick Flow as-cast 220cc cylinder heads
Generally about 10rwhp less than the 215s but for a lot less. These run about $1600 assembled.
