question about 305s
Dose anyone know if there are like vortec heads for a 305 or any type of better flowing heads for a 305?
|
Yup. They do make a GM vortec for that engine. Summit sells them, as do alot of other retailers:

if your gonna buy new heads you could just buy a used 350 and drop that in instead of modding a not so well designed engine (performance wise) thats just my opinion and what i plan on doing when i can find the right car.
|
I always thought about taking a Stock 400sb head and putting it on a 350. but prob work on a 305... they have Larger Valves.. and dont cost as much as aftermarket stuff.
|
the 400 heads suck on the 305, it kills the torque, and lowers compression some too (just what the 305 needs is less power)
|
it does? How do you know that? Experience?
|
yep, the other issue is sealing the 400 chamber is bigger than the 305 (over .090 if memory serves) so part of it is not gasketed
|
i dont have the skill or time to mess with swaping engines i was thinking about doing a stroker kit to 312 i found for a grand n thought i should change heads too cause somwere i saw said if u stroke a 305 u should go with better heads cause the stocks ones dont flow good enough or somin like that

|
a rebuild will cost you figure $1500 average if you do it right (with machining everything)
|
