Inliners International Forums General Discussion Engines 292 cylinder head valves?

My engine is an assembled shortblock at this point and just lacks paint but I'm still working on the finishing lumps in the head myself and I already had it machined for stock size valves several months ago before i cut out the bolt bosses. I talked to tom lowe at one point and he recommended that I could keep the stock exhaust valve size but maybe have them increase the intakes from 1.7 to 1.84 IIRC. I believe that's the next size up. The brand of valves the machine shop already got me are SBI. This is because of my lack of parts knowledge before i ever had them start. I looked up the SBI valves website. Some guys online refer to the brand as "rebuilder style" and they are made in china. Should I be okay with them or can someone tell me another brand to use instead maybe?

Many people have a preference. I have never heard of SBI, and probably wouldn't use them even if they were recommended by a competent shop. I prefer Manley or Ferrea. Tom uses Ferrea also. Many of these companies offer a street valve that is lower cost as well as high end valve, so they have what you need for any budget.

I spoke with Tom last night and he told me that the SBI valves would be okay for my application since i'm not going to rev this motor over 5,000. I ordered his roller rockers and rocker studs too.

We also did used that the boost will be limited to 5-7 psi. Another thing to keep in mind. Boost will not be continuous but sporadic. This will not be hard on the valves.
