Will work great in a 4WD... But in a steet car it will suck but can be useable none the less, just very RPM limited...

If your going that far why not find a set of large ovals...? They are not that expensive and with the aftermarket valves you mentioned they would really give you neck pain... (the good kind)

Yes all of the large and small ovals come with the smaller 2.07 intakes and 1.70 exhaust valves... Seeing how your location does limit what you can aquire then they may be a good app for you...?

Hey figure out how to get them shipped and I have 4 sets of either 049`s or 781`s I would let go for $150 US per set (bare heads)...

Hehehe... State...? Why Texas of course...

1 set of 049`s are hot tanked and clean the other pair are dirty... The 781`s are hot tanked as well but are slightly different, one is a 781X the other is just a 781 but look the same... The other set I have is a set of semi-closed chamber heads that I`m saving for another project... All need guides but seats are all good...

049 or 781 might as well say twins... The came on the same HP engines over various years...

At 9.0:1 and a "healthy" cam, you'll definitely notice that the peanuts suck. On a truck with 7.8:1 and a 1975 cam, they'll be fine to 4400 rpms

I agree... hard to beat the 049s or 781s. Very little difference in my opinion at this level.

Peanuts is the things there is in turds, right?
Buy a decent set of used heads, and you will be much better off. Proberbly cheaper then overhaul the turd heads too.
Good luck with your project.
