I think the bigger question is,"What do valve seals have to do with a 1angle or a 3 angle or a 5 angle valve job?" These are two different sides of the stick.dnhieu said:no body knows the answer to this question. i know alot of you people have added a 3angle valve job to your head rebuild
thanks

Slowboy said:Standard valve stem seals are used regardless.... all of the valves have a 6.5 mm stem, this does not change regardless of the type of valve job.
When you go to a larger diameter valve, we use a SERDI 3.0 with a radius cutter... which is a lot closer to a 5 angle valve job than a 3 angle job. This is done by opening the stock valve "seat" to the required diameter. The stock seat can easily go 1mm over.
Most well equipped machine shops can handle this type of work, however the wrong valve job on 1 mm oversized valves will flow WORSE than a standard valve...
Hope this helps.
MGH
because he told you something that most people already knew? Dont get me wrong slowboy is a good company but thats not really advanced.dnhieu said:this is the reason im going to spend 2200 dollars with this company

Or, the ½-mm needed for 1mm-over valves.Slowboy said:The stock seat can easily go 1mm over.

dnhieu said:but let me get this straight...
if i ordered stock valve stem seals, bronze valve guides, and 1mm over sized valves all this could be put into a head with a local machine shop just milling out the seats to get the valves to fit?
thanks

David, there's really no need for big valves and a modded head if your car profile is accurate.dnhieu said:the topic says what im looking for. also what kind of machine work is needed to fit 1mm over sized valves?

Yeah for real. Especially a 1g head.gsx951 said:Engine rebuild or massive turbo and exhaust?
With a 16g and a 2.5" cat back, a stock head is yawning.
