The 186 is a great head in terms of vintage small block heads, but at this point it's just old...(Not a hater of double hump heads, I have a set of 492 completely worked on my Camaro that make good power but they cost nearly $1200 to build in the mid 80's!)

To my knowledge, all of the 186 heads have accessory bolt holes. I have a set on my Jimmy (actually a 186 and I think an 041? Same head different casting that replaced a pair of 186 that munched a seat when a guide failed. Cut into water trying to fix that head so junk.)

There is just no way to do cheap heads unless you can do them yourself. By the time you buy them, buy valves, pay for hardened exhaust seats, valve job, guides, cut spring pockets (if needed) get springs, locks, retainers, vatted heads, surfaced, minor port work or manifold matching, screw in studs and guide plates, you've spent a ton of money.

Just keep pinching pennies until you can afford a set of AFR 195's.
