Default paging PSJ...

i tried to search on some info about the allpro heads and couldnt come up with much of anything... i know your using them....

i saw that they are making a 6 bolt per cylinder now....

what do these flow out of the box?
did you have to use after market valve covers or rockers?
how much did you setup cost and what is it.... intake cc? exhaust cc? have any flow bench numbers by chance? who did you hand porting on these?

Thanks,

Tyler

I'm using stock 1999 valvecovers. with stock rockers:

Mine are not cnc ported, I recall that they were flowing in the low 300's and 220's. Mine are like 70-72cc, and I'm running Inconel exhaust valves.

Your best bet would be to email Bob @ AllPro, and see what he says... I'm not sure most folks would go for the Inconel valves.

But that's interesting that they have 6 bolt heads, maybe I'll get another set for my other shortblock.
