Head removal for inspection (UPDATE with pics)

Cool. Any idea of max revs it's pulled? Just thinking of those springs.

 

Limited at 8400 rpm, no issues to speak of yet

No idea what springs dan used but i would imagine he would have gone for best ones

In past i have done some agressive down changes with revs deffo going over 8.5k and all is well

 

I'd definitely recommend changing them then, with a rebuild effort like this

 

I will speak to Bill as i am sure some valves from supertech are only matched to certain springs and collets or something like that, something to do with beign one groove or more

Not entirely sure, cheers for advice Chris

 

I love that - and my 8v won't rev over 6k

 

9krpm baby.. 20vt with bt luv it - muaha ha ha ha haaaa

 

I agree!

Bill, i dont suppose u know what valve springs Dan installed during valve gear upgrade?

Also are you still on hydro lifters?

Cheers

 

did dan get them from me do you know?
i can check the order and see if it said single groove or 3 groove style

hydo on mine yea. been ok
motul 300v oil used tho which i am convinced helps them cope

 

No idea if he did Bill

Just goes to show what revs hydro lifters can cope with!
