Hi Matt,
Thank you for the prompt reply, I'll get busy with the die grinder then.
I have a set of Manley Valves ready to go in.
How much clearance do you recommend?
Are you suggesting running the exhaust valves with no viton seals or have I misunderstood your reply?

Hi Matt,

I'm building a blown 350 sbc for my competition coupe and have some early Dart/World Products iron heads that have a really nice porting job done on them, I've fitted new bronze guides and now not sure whether to blend them in or just leave as they are, the engine is a 550/600hp pump gas motor with a 6.71 and 2 holley hp carbs so not looking for extra power just don't want to screw up the porting job but equally don't want to restrict the flow either.
Thanks for your help.
