If you not after The extreme CFM #s you can do a good blending of the port Bowl(clean up any ruffness taper/round off the Valve guide Boss,Gasket match the Port openings. And not have to worry about epoxy blending the Lumps. And you will still see a very good Increase in CFMs. But If you are after the Extreme cfms then Blend the Lumps into the port(clear to the back) remove the Valve Boss Or Blend it to the Point of (lets say It was removed).But If you do remove the Boss a 100% DO NOT CUT the Guide off Leave it in the Port.YES the guide would still be in the same Location It just won't have any Boss around it.
But as a good Hot Street or daily driver I wouldn't be to worried about going to the Extreme side of things. Unless You have ran a Motor with Out this Modification and KNEW your Motor That well.BUT had Just built the motor for the first time with these head Modifications You wouldn't know or feel the differene Between a HOT Street and a All Out Extreme Race FLOW Head. BUT to go from a Stock Head to a HOT STREET Yes you would feel and see a difference.
THIS IS ONLY A EXAMPLE(food for thought)
A good example of a good Hot Street Head is stock Or 1.8 valves intake. Exhaust stock 1.5 or 1.6 a nice 3 angle valve job cleaned up ports with a lump added to the Ports & a good example a Hot Race setup would be the 1.8 or 1.94 Intake with 1.6 exhaust a fully Ported Head lumps blended Valve guides addressed add a 3-4 angle valve job. BUT it is best to address the whole combination
Intake,exhaust, Cam, Carb to make the whole Combination work like you want And only have to do it once.
Hope this helps }[oooooo]
