my heads on my 302 i need to find out if they are 4v or 2v as for i am looking at a new motor with a 302 need to know wether the exhaust will hook up now they have a 2 cast on the 5678 head inside the little crevice on the front of the head and then the 1234 head has a 4 cast in the corner near the number one exhaust near where the head connects to the block some replies please these haeds may not be originals they could have been put on afterwards as the car did use too have a fully manualised auto with hi stall in it

Most unlikely they would be 4V's.

A 302 would hardly run with a 4V head, it would have to be fully race prepped to work with them.

I don't recall any Australian made 302's ever having 4V heads, so unless you've got some sort of wildcat heads on your motor they'll be 2V.

thats what i am saying i need to know if anyone knows anything about the castings the engine is dead after getting a hidng while running cheap oil by the previous owner and it used to have a pretty wild driveline in it till the previous owner took it out and sold it but i havent been able to open it up and see if the engine has the matching hardware to the previous wild driveline so they could be 4v i just need someone to tell me if they are going by the castings

that 2 and 4 doesn't necessarily mean they are 2v or 4v, I have a set of 2v's with the same castings on them, another set has 3 stamped there instead. You will have to pull an exhaust manifold or your inlet manifold off to find out mate... You will know if they are 4v cos you could squeeze a tennis ball in the port if thats the case!

ok 302 C's never came out with 4 v heads and unless someone put them on , they will be 2 v. as you look at the front of your motor you should see a "2" in the little void at the front of the head casting, that means it's 2v. those 2v's should be closed chamber, and they are great heads, they have huge potential for big HP down the track!

Drop off the extractors off and look at the port !!!
