int/exh vavle upgrade choices
upgrade intake/exhaust valves. they are getting a little harder to come up with than they used to be. so.....
im thinking about just having some made. cheap enough at around $20 each. incolnel of course.
were the aba's the ones with 7mm stems?
here is what im thinking. 7mm stems, knecked down to 6mm. 42mm intake valve, and 35mm exhaust. titanium retainers and 8k rev springs. along with p&p. . . . should be the ultimate 8v head
have you already upgraded everything else? valves arent really a restriction until you have ran out of other ways to easily get HP..

last build was just port and polish, bowl work, 268 cam, header.
now its getting the 1.9L treatment with custom stage 5 digi 1. 440cc injectors, 65mm pulley running 18psi on custom built charger and water meth.
probably the last 8v build i will do for quite some time. next time. . . . its going 16v
sounds like this is a pretty WILD build.. lol..
good luck with it, let us know how it goes!
