I always measure everything - double check spring closed height and pressures - check for coil binding etc.
I never trust anyone - measure, measure, measure.
I think when I first spoke about this new build Gary said to use 3mm spacers.
Yes I can buy uprated springs but when I dont need them thats £300 saved.
But yes Perry I should of checked before fitting the head!
lol

Ah I see, thanks Rick! Are you 100% sure that the gasket can be reused? Will it still compress like it should?

Remove the head, check the clearances on all the buckets, and you might even find you have another one upside down too, I managed 3 the first time i built up a st170 head.
Looks like I'm taking them all out so I will make sure they are in the correct way up, thanks!

Mate there is no need to get the arse hole with me, you replied with a very generic question which made no sense hence my reply.
Had you of said, the spacers are not needed and thats whats wrong I would have understood!
