Just wanting some opinions on this stage two job with 2.02 1.6 manly valves. Before numbers were stock valves with an old stage one thunder racing CNC job.
Sorry for the fucked up pics was having a hard time with the lighting
They are 853 castings.

 

ttttt

 

What are your cam specs?

 

Not bad, but i've done better.... on a so called "stingy" bench

Oh and did they back up after .650?

 

I'd say they look pretty good! A lot of heads I see backoff after .600 but these keep climbing. I'm sure you won't set any records with them, but for what they are I believe you will have some good numbers.

 

Well, the heads can keep flowing all they want up to 1" lift, but his cam specs are gonna determine whether or not the head porting was worth it in terms of lift able to be utilized

 

yes but heads that back up usually dont make as much power as heads that don't.

 

cam specs are 222/224 .581/ 114 rockers are 1.75 comp pro mags

 

At your max lift it looks like the heads will be flowing in the upper 290's. These heads would probably benefit a low .600" lift cam a little better, but should suit you pretty well.

 

heads are now going to be used with the new Hi Flo turbo kit I have received I think I am going to use this cam with the turbo since its on a 114 lobe separation. They made 415 Na now its time for 650 with the turbo on pump gas.
