looking for suggestions on what type of manifolds to use on my 68 Lemans. Engines out of a 67 grandprix with 670 heads. not enough knowledge yet to know if i have square or round port heads
which type of manifolds do you recommend
and where do I get them?

I think 670s are square ports.

Whaddya doin' with the car? If it's a cruiser, stick with factory cast "log" style manifolds (a dime a dozen), or gain a few HP by using cast factory RA manifolds. Use RA "longbranch" manifolds to avoid leaks like many headers develop.

Otherwise, I think Doug's Headers are the very best money can buy, and reflect that in the price. Fitment of headers on your car may be an issue???

If you go with the standard manifolds, you can use pretty much any 64-72 GTO, Tempest or LeMans standard manifolds.
