Backcut the intake and exhaust valves, grind a bit below the valve seat into the throat--but not over 90% of the seat angle then blend that into the bowl. 92% is MAX! anymore will destroy the flow. No more than 15 degrees between seat angles.(Example is 30-45-60 valve seat angles) Grind a bit off the pushrod pinch point but not so much as to thin that section out. Gasket match, remove all casting flash around the long side radius, finally I hand Lapped the valves just to make sure they are seated and sealed. Thats it. I increased flow approx 10% for both intake/exhaust thru the lift of my cam which is .600 I didnt touch the chamber. (A lot of the newer alloy heads have a ridge around the valve seat area on the head,,this is an anti-reversion ridge and should be left in place and NOT smoothed out,,this is to prevent fuel puddling and improves wet flow) The fel-Pro 1009 4.441 .040 Head Gaskets clear the chamber and fit the 4.375 bore nicely. There is NO overhang into the Combustion Chamber of the head. I am using a Roller Camshaft with PAC Beehive valvesprings 225/400 close/open pressures with their spring cups, tool steel lightweight retainers, 10 degree locks, and their special seals. 425.00 for the complete package. Hope this answers your question Ian.

thanks for the run down eddie it sounds like your doing just enough rather than trying to gain to much & loosing velocity as many do
i also will only make small changes to my ports mainly just a clean up of the outer radius & bowls & gasket match & mabe blend in the valve guides
i havent had a chance to get anything done in ages with work comitments its been a pain but i get home from work & just dont feel up to doing any thing more but the winter will be here soon so ill have shorter working hours mabe then ill make some progress
cheers ian
