The procomp are junk out of the box. Get a good machine shop to redo them and then they are not bad at all. I have use a few sets with no problems yet but it's probably more of when they fall apart not if. But I have set under caution while bits and pieces of dart heads and dart block were picked up off the track. Just cause they are name brand don't mean they are not going to drop valve or what not.

if someone would like to step up and buy me AFR or Dart heads feel free, if not I am using what I PAID TO MAKE RIGHT.
now, if you you guys said they suck and I said "nah they are fine" then I see drillin me... but thats not the case here.
GELLNER is not a hack shop and no name person, I trust what they did to my heads.... they are fine... Any head can lose a seat or whatever, at least I did what I could...I dont have open checkbook here...

Geez, cut the guy some slack! wasn't this thread about proven recipes for 540s? Not what heads not to buy? I too sank a lot of money into making less than ideal heads work, not all of us can keep throwing that extra 5K here and 5K there at our boats!
I am with you Full Force, sometimes you are in too deep at the point where you shoulda done xxx, and you make do with what you got.

Ignore the noise and follow your plan..... As I said before, these heads are fine for a normally aspirated build .... Thousands of these heads are running on the street every day....... Boost and super high compression with high rpm or crazy valve spring pressures are not what I would run with these heads...... Most failures occur because of these issues. I did my research......... I have these heads, I worked these heads so I have real world experience and not second hand rumor ..... My engine is a 502 with a dual plane intake so I was
After making big torque numbers. I have 10.2-1 C/R and a nice HR cam from Bob M anda marginal 496 style exhaust and I feel i am around 600lt/lbs TQ.........With the HP numbers you are after obviously you will need a good HR cam and matching springs. Good single plane intake with a good exhaust and I see your 540 making 650 plus all day long at moderate rpm levels....... Hopefully others will share their combos... Good luck with your buildup!
