back cut
Monday, November 30th, 2009sorry to ask but what does the term back cut mean is it another angle after of before the 45 degree seat face
regards Roy [ uk]
i see the below posted a while back
Typically a backcut valve will hurt the wet flow of both race and street engines. The best thing to do is find a valve that has the proper seat width without a back cut.
Performance Valve Job
Monday, November 30th, 2009Joe- On a fully ported head what type of seat cut makes the most power- a cut using a multi angle cutter or several single angle cuts. Is the difference really that great? Building a streetstrip type engine and don’t need every last hp.
Thanks

Do you have any suggestions on a multi angle cutter for this particular head on both the intake and exhaust. There has been little port work done and is used on an economy modified 2WD truck puller engine. The engine is a 460 bored .080". Any suggestions would be greatly appreciated.
