    Well I'm undertaking a big project next week: Remove the head. I have a 1.5mm Cometic headgasket and ARP headstuds coming next week. Any tips on keeping the timing? Any things I should watch out for? I dont think this should be too bad, just a little time consuming. I think I might as well swap out my oil pan while im at it too!:D I'll be sure to get pics and what not!

    Should be pretty straight forward. Disconect the battery so if someone "accidentally" turns the key, the starter wont engage and screw anything up. There are marks on the cam sprockets and crank so you can line everything up.

    Would it be a bad idea to maybe just "polish" the exhaust ports myself? I know there is a bit of science when it comes to porting.

    Yeh, I wouldnt expect that much. Im hoping the 15psi of turbocharged air will fill the void!

    The 1.5mm gasket should lower compression a little bit. Considering Luis@Paradise Racing said that a 1mm gasket would work fine for 15lbs

    Its going to be a process for sure! Still have to find suitable 440cc injectors and wire up my Emanage. The tuning is going to be the longest and most time consuming step in the boosting process!

    Why 440 injectors? Seems a bit much, any concern for propper atomization of the fuel?

    Stock are about 320cc, I would be maxing the duty cycle out @15psi. Most guys with the same plan as me have gone up to 550cc.

    Actually, it may be... Im not sure, I was just told that the 440cc would be the largest to fit in the stock injector rail. So thats what im going to go with, might was well go big all at once!
