head porters a little help please

I am building a 273 (and will do whatever you say:)
It is for a streetcar but will probably take it to the strip sometime. its going in a -68 Valiant with 904 and 3.23 gears with 340 ex manifolds, and probably a Tci breakaway verter.
Cam is small comp 268h.
I know its not much of a racecar but i really want to make it as fast as i can.
I got cam and carb and compression.
I plan on going with the 1.6 ex valves becouse of the poor stock valvejob (only one angle) and becouse i dont see how it could hurt.

Question is would i benfit going with 1.88 int valves?
Ofcourse with cyl bore notches.
How would you do the heads for this build?
As said its not a real racecar but please help me out here.

if you have to use the 273 heads, then yes it would be good to bump the ex to a 1.60 valve and pocket port the bowl

I better head would be a closed chamber #302 318 head

cant hurt go with the 1.88 valve,but the shrouding is the hold up in flow..even with bore notches

I have just went 1.60 ex and hoged out the ex bowl/port on some back yard engines,that gave a good bit of pop to it for the effort

you gonna flow bench them?

yes i prbably will.
But i would like to have them flowed fisrt with the 1.78 and then with the 1.88
and since this build has cost me almost nothing flowing the heads will be the most expensive work.
I just finished porting one ex port and to me (novice) it looks really good.
a little more blending when the 1.6 is in.
Will get some pics soon but right now i am packing my bags to go to the Canarie Islands (sp) for a nessesary vacation

well then,cant go wrong with a vac in the canary islands

enjoy the break and get some R&R,drink a mi-ti for me
