I'm bulding LS/VTEC turbo in my sol. 2 questions....

since im using the ls block, the oil passage to get to the head is blocked because the LS does not use VTEC and i guess does not need oil to go to the head, but im putting the gsr vtec head on it, therefore i need the oil passage opened correct? and how do i do that?

next question...

I bought ARP head studs and 2 of the studs are longer. i think this may have resulted in the ls head having the need for 2 longer studs but the gsr head seems to me that all 10 studs need to be the same length. both arp and the company i bought them from cannot help me.

Please help me with these questions, thankyou
