Thanks spool, yes I am mechanically minded, I have rebuilt a few engines, I wont be doing all the engine work myself, I will just be there with him lookikng at what happening and finding out things I havnt yet found out about on or in the engine, the bottem end will be sent ready to to go so its just doing the top parts, I want to mainly do the plumbing and bolt on parts and do a few mechanical stuff providing I have the time to get there, as its 400km away to where I live to do it, im not sure wether it makes a difference to get my heads ported, but I am thinking I will do it, any suggestions with this??
