ok i have a set of 853 heads i had ported a few months back is it worth it for me to have bigger valves put in them? i was thinking about going to a 2.02/1.60. i have about 800 bux into the heads with the crane daul springs on them so i really dont want to go out and spend the money on new heads if i can get these closer to them by putting bigger valves in them.

thanx

 

I'm in the same position you are. What cam do you have, or getting?

 

i'm in the same predicament. the heads i'm using have 2.00 and 1.60 manley valves but i have a set of 2.02 ferrera's i could use and i need a valve job anyway. should i put in the 2.02's when i do the valve job?

 

In many cases you can gain as much flow by getting a good valve job, good bowl work, and using your stock valves. If you decide to go with the larger valves, give us a call we can give some great prices on Ferrea 6000 series valves.

 

well my current setup on the car is stock ported 853's with a comp 5 angle valve job and a custom cam motion cam 234/240 .627 .641 112lsa. right now the valves clear the pistons but if i go bigger thats going to cut down on my ptv clearence right?but if i pull these heads back off im going to port match them and do a little more work to them and do the bigger valves.
