Okay here is the deal. I ended up cracking one of my LE2 heads and I was planning on swapping them this winter anyway due to the Compression being around 9.8.
Now I NEED a 58CC MINIMUM head but perfer 62-64cc

Also budget is HUGE as I just bought my first house.

DO NOT TELL ME TO GET STOCK PORTED HEADS BC I CANNOT RUN THEM DUE TO COMPRESSION!!!

Currently I have a 383 LT1
Eagle 3.75 Forged crank
Eagle 6” H-beams
JE-28CC pistons
Ported LT1 intake
1.6RRs
Custom turbo kit done by myself (1 5/8 log headers)


Current power 583rwhp/491rwtq (8psi)
Goal 700-800rwhp
Plans 15-20psi

Okay go ahead and bash me.

First off

Patriot heads (My buddy has ran them on his 450+rwhp NA LS1 car for 2 years no ZERO ISSUES)

I have spoken with them. They are their OWN CASTING.
He will make them anywhere from 58-64CC for me (perfect)
2.02/1.60 valves
Titanium retainers
0.650 lifter Gold springs (everyone seems to love them)
They flow better on the exhaust side then a trick flow and just a tad under on the intake side (no a huge deal as ill be forcing air in haha)

Second option

Trickflows
2.02-1.60 valves
Now they things I don’t seem to like is
Springs will be of no use to me (so another 300-400 on top of the 1299us)
They don’t flow as well on the exhaust side down low.(big deal being turbo’d)

Last option

Ported AFRs 195cc(used)
2.055/1.60 Valves
65cc (will need to mill as my compression would be at around 8.60 and I wanna stay around 8.8-9.1)
1200 (used) don’t come with springs so another 3-400)

Now the main reason I lean towards the Patriots is they have the best valvetrain setup. They flow okay (nothing like an LE2) but I cannot use stock heads and these are unported anyways. So I could always make this up. And the price $995 shipped!!!

Also darts would be nice but there outta my price range.

Also the AFRs I have to buy in 2 days or i wont get he deal from the guy. trickflows and patriots I can get when I have all the money
I move into my house in a month and wanna pay bills down so the patriots and trickflows seem the smartest option as I can wait till xmas bonus time haha

Now everyone has been bashing the patriots BUT these are all people that do not own them and probably can afford to get the best of the best.
I did read a thread of a guy that bought some and said the quality was amazing. he hasnt installed them yet bc he wanted to bench flow them just to get real numbers bc all the bashers said they dont flow and they are junk etc.

Comments?

darts?

TFS 21 Degree heads?

Other than that I would go AFR. Very old but proven.

It really is hard to answer the question unless you truly set a budget. From the sound of it though, you want the most bang for the buck. I know you seem set against a stock casting, but there are benefits to running the stock casting. After a head has gone through several heat cycles it is less likely to warp or crack, assuming the porter inspected it. And these heads can get very good flow.

If you are set on aftermarket heads, my understanding is that Trickflows may not be the best out of the box, but actually can flow better than AFR's with some port work.

Thanks I went with the AFRs bc I sold my cracked heads to a guy that wanted to fix them

PS mat its Jay (i met you at one of the mifbody meets 2 weeks ago)
