These casting do come with seats and guides installed, but will require the guides to be sized and the seats cut to the users valve train components.

well at least thats an idea of what we're talking $ wise. So it looks like economical (not low quality) you go with Dart and for high $$ high tech it's either Edelbrocks or AFRs and then race you go with the ET's. and any where from $600 a head to almost $2000. Well at least there is a range for everybodies pocket.
Still none of the forum head Gurus made any comments on the flow numbers, I'm looking for some educated opinions.

I just spoke to the guys at Edelbrock yesterday about another project and asked they confirmed that they were at Lingenfelter getting ported and said they should be available late November (but added that that was a tentative date) Soo everybody should put them on there Xmas wish list and see if Santa will stuff the stockings with these puppies. Also I just bought a set of the E-tec RPM 200cc heads and they look BAD *** they came out of the box CNC gasket matched and got SS valves double springs and I think titanium retainers (need to confirm that) To me the heads look top notch and once I get the motor running I'll see how they run. Should be BAD ***.

I hope to know soon what works, what doesn't and so on. This willbe done on our engine dyno so you will know flywheel hp on several different set ups!!

you may want to take off the S on head(s) on the price listing page, may cause some confusion.
