: Thanks for helping me look. I have many questions? Where have you seen heads for $100-300. I live in L.A. So is $750 0r $500 the going labor for the head replacement? And How does the valve job fit into this? If I use a 535 engine mod kit do I need? Thanks again.
... the thrust of what you want to do seems to be to get the car running at a reasonable price? If this is so, then forget the engine swap to the 3.5 liter. A new head runs around $900+ , from experience if you dig around you should be able to find a good used head for under $300. Dig around, frankie down the street may have one for $75. A caution is that the used head you get has to be good, no cracks ,cam towers not worn out, not warped, valve seats serviceable, valve guide bores serviceable. If you dig you might find one that is cheap and only needs a little valve seating work. I would say that $500 is the going rate for labor to do this job.I would not do it for a whole lot less. This assumes the good used head does not need new guides and seat work. Add $175 for new guides and seat refurbishing. So you are at $675 plus the cost of the head. Come to think of it put on a new water pump and all new belts(including the cam drive) and hoses while you are there. I am also assuming you have a non-dealer shop. Only warranty work and some diagnostic work should ever go to the dealer. You still got the bug for the 3.5? Add more dough. Hey, I buy my parts from germanparts.com , they have the best price not all OEM though.
