i'm tring to decide which valve i should get for my turbo h22. what are some problem if i decide to go with the 1mm over? i'm planning on running about 600+hp. using cp pistons. i talk to portflow and they said to go with the 1mm over for a turbo h22. what do you guys think? what are you guys using for your tubo h22?

 

if you go 1mm over, you risk the chance greatly of the valve going through the valve seat, which is a hard thing to fix from what ive read and seen. i got mine .5mm over and i didnt need new seats but if you do it, just make sure you have faith in the machine shop.

 

i'm gona have exospeedAMcrx do the head work. what do you guys think about them? anybody else running 1mm over??

 

my head is at the machine shop with 1mm exhaust and .5mm intake. i'll let you know how it turns out.

 

why did you go with 1mm exhaust and .5 mm intake? why not go all 1mm over? just curious why you wen this way.

Since turbo relies more on exhaust side so I thought it would be more effective in going with 1mm exhaust to expel the heat. As for .5mm intake my head will receive minor head work which effect subtle results.
