Re: 1/4 update
good stuff xb351coupe! thats a good bit better after the last run..
can't wait to have a go myself!
what are you thinkning about doing with those standard heads?
i guess it depends on whats already been done if its worth-while porting them or going alloy's.
If you have all the valve train to suit your cam, already paid for harden seats? then a little bit of porting isn't going to be anywhere near as much $$ as alloys. not as good either though.
Just to have a play with mine i set a limit of $800 of head work that last time.
that included fitting larger valves, 4 angle intake, porting, decking and some bowl matching (minor)... that gets me 480HP flow... but they will only give you an est of flow before porting for that price, then only flow 1 or 2 ports on each head....
