Ok so I have the chance to make a trade for 220cc Trick Flow's milled to 61cc.

Would these work on a stock LS1? Also I'm going to be putting my D1SC on soon so would they be best in that application?

Not too up on my head specs.

Might do a blower cam too.

 

They will work on the motor but typically you want to lower the compression with a blower. The 61cc chamber will up the compression to around 10.8:1. You might not want to go that way unless it is going to be a while before you go with the blower.

Those heads will raise your compression with the stock LS1 pistons.
Which will limit how much boost you will be able to run. Which you can still make alot of power with a supercharger and higher compression.
My guess is max 8-10psi of boost safely with those heads and factory LS1 short block.

 

I plan on putting the procharger on asap! It's been getting put off since October of last year!! hahah.

Ok, thanks for the clarification.

So what should I look out for in heads to lower my comp ratio and work well with a blower cam.

Springs/Lifters/rods and all. I'm a little slow on this stuff.

Any info/suggestions would be greatly appreciated!

 

Seems like alot of people go with GM 317 heads off the truck 6.0's.

 

some 317s and the brute force blower cam would make great power with your D1sc
