Hi, Pic’s are showing blurry w/ low light. Can you please post a few pics showing the Intake ports, Combustion chambers, and one end? Was Pretty sure of what they are, one pic has me second guessing that theory..
TY!

Man I’m pretty sure those are an old set of street heat heads, which are actually an in-line style head - not twisted wedges.

No, don’t believe they are TW’s either, they have been running staggered Valves off centerline for a long time. Time has changed them, not terribly. Pic isn’t great, but you can see the obvious difference(s). There’s got to be an ID # somewhere, wanted a pic of the end of a Head to see if Valve cover surface was elevated or at Stock Ht., Valves & Chamber design.

Exhaust Ports are massive vs.TW’s, don’t appear ported. If prop
Can anyone tell me what kind of heads these are?
At First i’d thought these to be older TrickFlow HighPorts, very similar Exhaust surfaces & casting radii around Plugs, but they didn’t have dual bolt patterns on Exhaust ports. Zoomed, the 2nd pattern is partially visible below front & rear port Header bolt holes.
Somebody may have plugwelded them, Aluminum Epoxy, etc. If no numeric markings exist, level the Intake surface plane & fill an Intake port with Water with a graduated dropper (CC’s), do the same w/Plexie siliconed flat over a Chamber, hole in center- level plane.
Those #’s, Valve diameters, Pic’s of one Head’s end, 1 of Intake Ports, 1 of bottom of Head will make it relatively easy to ID these with certainty. Even pics would help for now.
Below are 2 Pics... 1 of a High-port Head, other- your Pic enhanced showing a broken Spring, noted while searching for ID.
TY -John.

The original high ports actually only had one set of header bolt holes.

I think these are just the old school hps

Yup- I agree. The (4) independent & angular shaped Exhaust Ports, clearly raised upwards seem to reflect HP’s. Didn’t know the older ones were single Bolt pattern, but spotted what appeared to be previous Bolt holes partially covered, highly Zoomed in.
Based on Exhaust port size, I’d venture a guess - Intake CC’s to be 190-205.
Irritating when one starts a thread with a query & doesn’t respond ONCE to requested insight.
Life gets in the way- I get that- otherwise, pretty freakin’ rude, IMO..
