2 sets rec port heads wanted iron ok [email protected] Andy

Gen 6 ?

Mark IV or Gen V / VI

I have one set of Gen 6 for 500.00 and one set of Mark 4's for 400.00 The sixes you can put right on, the fours I would redo they have been setting for 8 years inside

I am going to be selling my Wedged and fully ported Merlin iron heads. (JimV Valako Race Heads) They made 590HP on my 454's
I am going to be using Jim's new aluminum Dart marine head.
How much you looking to spend?

i have 2 sets of AKR 340 aluminum heads with dyno time only on them... sd 2.300 manley in, 1.88 inconel manley ex
crower roller spring, locks and retainers...
both sets ready to run, just bolt them on install your rockers and your off to the races... lol
looking for $5900 for all 4 heads... will not separate, they are still on the engines, reason for sale is I want to run 380's

I know I am opening a can of worms here but wny rectangle port?

Oval ports make more low end torque

Rectangle is a better high RPM head. just figured Id ask, each have thier use.

Do you want bare heads only or fully dressed heads (valves, springs). Mark IV. I have two new sets of Merlin Rect. port fully dressed ready to go. Going fresh water cooled on new engines and now want to go with aluminum heads.
