There was a problem filtering reviews right now. Please try again later.
They needed quite a bit of flashing clean up. Using cartridge sanding wheels, I was able to get them smoothed out for flow and very clean. I put new springs on and lapped the valves. Installed height was 1.70 just as stock. They were incredibly flat when the arrived! Less than .0015 across in every direction. I got long tube headers, too, as the original exhaust flanges were rotted away.
OMG! The car picked up a ton of power! Just amazing. It is just mind boggling how much more power it has with these heads and headers. All the way through the RPM range. You really notice it above 3000 rpm, though. The cam comes alive around there, so these heads really breathe and let it develop so much power above 3K! I wanted to do an LS3 swap, but now, I can wait, as these heads and headers combined to make the Mighty Mouse motor put out big block power.
These heads get 3 stars b/c of the price, you can get the machine work done and build your own valve train to match your application. And these heads will still be probably half the price of the cheapest fully assembled aluminum heads.
Expect to have to get aligning spring shims based on your own spring choice. Plus you will have to get +.100" length valves for an accurate spring assembled height. The push rod holes are nowhere, and I mean nowhere, close to being centered on the pushrod but don't rub so maybe we will go with lightening weight.
These heads look fantastic out of the box, but you should check and verify deck flatness. You are getting what you pay for: Chinese quality aluminum cast heads; cheap, not perfect, needs some work to be great. Never get these pre assembled like you find sometimes, use quality valve train components, you'll be glad you did. And even with all that, you're still ahead when it comes to cost vs a high quality aluminum head already assembled : $1200+ for an individual head. Overall 3 stars... for now until I get the engine running.
This is my 2nd set of DNA heads and 1st set works well on the 427cid stroker engine.
I am hoping these will work as well on 383 cid stroker.
Hoping to produce a little over 400hp should be no issue if these perform as well as last set.
