Went for a run to WSID last night and posted a PD of 13.232 @ 103.47, my previous time was a 13.5. Only change was a rebuild on my LSD after my last trip out to the creek a couple of months back the LSD died. I'm happy as the heads are only stock 2V's with a mild hydro cam and running an auto with 3.89's.
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....

Maybe next year I'll swap the heads for Alloy bolt on 2V's, not sure which brand yet (my rockers, valves, springs,etc will go straight on , I think?) a bare set are around $2200 which is not to bad, might even be cheaper by 2006 and a solid cam..say a crane F246, but no decisions made yet. I think that is a better option than spending more money on the iron 2v's at least the results are proven and you know what your going to get for your money.
