I was worried for a little bit there.....phew.

I have to wait till the end of the month then I will post up another thread on the whole job. Pictures included.
That way future people can refferance the thread and leave you guys alone. I just want to make sure there wasn't something else that I needed to be looking at.
I think pulling the core plugs and cleaning out around the cylinders is a great idea, I know they get buildup over time and without doing this I would have just crack the 0331 head again.
Thanks for all the help so far guys, great forum.

Worth it though.

Can't seem to find any info on this at all. Looked up head swap, custom bracket, coil bracket, and nothing, has no one posted a step by step of this yet?

To whomever suggested downloading the factory service manual from Pacific Coast Manuals......THANK YOU!!!! Absolutely the best $7.99 I ever spent!! Thanks and thanks again! Looks like I'll be returning the Haynes manual I blew $29 on.

some people say you need an adaptor plate for the exhaust manifold, others say you dont. heres a link if you do need one. he used to make the coil brackets too but doesnt anymore.
