Ok here's my story. I bought some ARP head studs from a guy. Told me it was for b16 motor. So I went ahead and bought it. I forgot to check the part number, my mistake. When I got home and notice the part number isn't right. So I went online and double check and it turns out its for GSR instead. So I'm stuck with this GSR head studs and wondering if I should just go ahead and install them into my b16a2 motor?

why does ARP make different lengths for the GSR and B16a/Type R heads? At the same time, Honda oem b series vtec heads have the same length head studs? I don't understand.

Thanks help is very much appreciated!!!
