How much power is possible through LT4 Heads ??
What head is currently running mid 9s NA in a 3400lbs car? And does it with pump gas friendly 11.7:1 compression. Far as I know nobody else
The DATA says this is a great option and the fact they are no welding CNC'd heads means you can buy the EXACT same thing this is not a one off.
Here is the "fastest LT1s list from this very site it is a sticky at the top.

the rest of the details on the car are in the link I posted earlier.
So who has an agenda and who is providing information on what actually works best?
The bench racers will tell you to start with some massive overmarketed head then grind the hell out of it till you can practically reach down the port with your hand. Looks good on the flow bench but not on the track.

An overwhelming majority of the fastest LTs in the WORLD, past or present, are running AFR heads. Period, as a fact, proven, case closed.
OP, run whatever the hell you want - but do your research and look at the parts being used in cars that have reached your goals.
Puck, look at the NA list, that is afterall the discussion here. The LT4s put up a better showing than AFR there.
Would be nice to see Abare's 200cc/LT1 intake setup there, would be number 2 and his 190cc/LT1 intake setup is faster than the current number 3.
Ed's and N2OPDAVE's setups are the only ones to compare to his LT1 head setups. Ed's is lighter with a LOT more compression, and Dave's car is a big heavy pig with SB2.2 heads so that is a completely different class on two counts.
