Title: Suggestions for porting heads
Post by: turbodave on February 04, 2021, 04:26:25 PM
I simply don't have the time to port the heads myself. Anyone have suggestions on a US based outfit that is recommended.
I know I can simply purchase from the wedge shop, but I'd prefer to work directly with the one who does the porting, not the middle-man. I also don't want to spend on a set of F85 heads - I need to keep the Rover heads.

Thanks!

Dave, F85 refers to Merlin headsIi suppose. I bought them ages ago to replace my home ported big valve Rover heads to and I was quite surprised how little i gained with them. Sure, on paper they were a major upgrade but even with mild porting they just did not perform. At that time they were reasonable priced, basically the same as having a set of std rover heads ported and machined and fitted with all new parts. The price nowadays is simply silly. Based on my own experience I would not pay that much money.

I am now replacing the Merlins with Wildcat heads. That has not been quite so straight forward as I thought...

Sorry, this does not answer your enquiry the least bit :-)

Worth considering the TA heads? Pretty good unported.

FWIW, I had McKensie port my Merlins,(Oxnard, Ca.).  We have posted the flow bench results here. AIR., about 220 cfm. in intake @ .6" lift.  Dan Jones, of this forum has all the spec's.     Art.

Art, have you fitted the Merlins to some engine. Would love to hear what they make in real life.

Jukka and all, Merlins are pretty "thick", so plan is a 6V-71 blown RV8. Likely a 4L. Going in my 51' Buick, led sled.,( 4" chopped but NO led ) ! Car is to "later" get an RV16. Yes there IS room since it had a straight eight.
