they look good too. Does Summit ship to Italy?
PS they are way cheaper than the ARP, I think I paid about $85 USD back in 2017.
I have to ask if the will. I asked jegs they do but the size that is not the same make me worry

My grandparents came from Italy in the early 1920s (maternal side) and became citizens in 1946. They came from San Donato di Comino....He was a woman's tailor....

yes that hole but I think AD meant do not use so much sealer on the end wall gaskets for the intake that it gets down in the hole for oil pressure switch. Some folks just use RTV sealant on ends and it can squeeze down in the oil passage.
Ah ok clear. Thanks

When I did that job, the main thing I recall was trying to keep everything lined up. So some Permatex Aviation sealer on the water port part of the cyl head will hold the gaskets in place while you carefully lower the manifold in place, then hand thread in the 12 bolts and torque to spec. If you need pix of the torque pattern I have them in my OMC shop manual and can take pix.
Now it is easier on the Vortec because there are 2 pins on the gasket and 2 holes in the cyl head, that the pins fit into to hold the gasket.
After that, you have to get the distributor in correctly, another little learning experience.

Mahle is GMs vendor for many internal engine parts.

Remember, the motor is a GM truck long block with marine gaskets and Mercruiser exhaust and accessories

Summit Racing and rock auto both ship to most countries in Europe. Usually faster than I get parts in Florida (3 days to Scotland, 4 days to Florida)

they have also other with different number of bolt i don't know why, in this case if i check the head is 113 ( efi model like my old heads) , but bolts should be same as per caalogue mercruiser

Car plug wires won’t be long enough to clear the marine exhaust manifolds so you have to use a marine wire set….

Search "custom spark plug wire kit" then you can cut them to length. Can even get a V8 set for extra in most cases for same cost

Could also look for 350 marine set if the V6 is to high, a 454 set would work also but wires will be to long

Thanks the problem is that i want to buy also head bolt. I checked in summit and bolt are 37€ but 57€ is delivering 😱 so i the car wire was same i could buy also that (33€) and save some money from delivery (here in italy the wire cost 66).
If you have some good name of local shop where i can buy both i would try honestelly in fron of this high delivering cost i would prefer to add other ithem as well
