TA / Wildcat heads

Re: TA / Wildcat heads
Casting quality looks nice. My heads from ACR are not that nice. I´m assuming there are no guides fitted because seats are missing.
There is a a lot of potential in the heads, should be an easy 300+ hp from a 3,9 litre engine.

Re: TA / Wildcat heads
Morning all,
I am after a bit of advice with your experinces with the TA heads for the RV8.
I set arrived in the UK for me after a long wait)). We are slow build on the engine - as these heads are new to me, so please forgive my questions if they seem silly (and pictures not in order of questions...!);
1. Who would you recommend for porting and finishing? They need done as TA don't have a porter
2. What did you use for intake and valley gaskets?
3. We know that the RRs they sent are not correct (so I am chasing to get these replaced, see pictures)
4. It says that you can use solid or hollow pushrods, but dimentionally, it looks like we can only fit hollow rods. Is this correct?
5. The oil way looks to be closed (see attached photo), was your assemblies the same, and did you leave them (relying on hollow rods) or did you machine that open?
6. Anything else important you you think is worth knowing?
Thank in advance

Re: TA / Wildcat heads
You can use “cut” down rover inlet gaskets, and standard rover/TVR exhaust gaskets
Mine have been extensively ported, rover won’t fit, so I have my inlet and exhaust gaskets made by
Ram gasket solutions, I used hollow pushrods, I bought my heads from TRS in Australia,

Re: TA / Wildcat heads
For the oilways - check on the block as there is only one, at the front of the engine if I remember correctly. But the head gaskets have two holes so you can use them on either side. Not sure if that relates to the missing holes on the head or not!

Re: TA / Wildcat heads
Many thanks for the reply B V8
How have you got in with them. Everything you'd hoped for or still room for improvement?
I'll be using them in a N/A set up.
Cheers

Re: TA / Wildcat heads
Pic of gaskets I use, with part numbers,
Please note, inlet gaskets come in different thicknesses,
Really helpful,just ring them up, and talk to them

Re: TA / Wildcat heads
At £100 a pop, I think I'll be sticking with my VAG 4 post coils for now

They can be had cheaper, or at least used to be a lot cheaper.scudderfish wrote: ↑Wed Sep 27, 2023 4:31 pmAt £100 a pop, I think I'll be sticking with my VAG 4 post coils for now
A lot of people using them, they are massive overkill. I don't think any RV8 ever would really need or benefit from them, even if it was like 14:1CR on methanol lol
regular OE LS coils can be had for sensible money if you find someone with good used units ( complete with brackets and wiring etc ), always best to buy genuine GM
But almost all half modern coils are very powerful, CNP does tidy things up though with no spaghetti plug leads everywhere, so worth doing for that alone IMO even if no real performance need.

Re: TA / Wildcat heads
I bought those coils over 10 year's ago. And i think they cost all eight approx 350€ ~ 300£. They are aprox twice vs vag coil bag 10 years ago..
Yes they are maybe overkill. But after that never had any issues of emission at MOT. HC is slightly over 200ppm without any adjustment. And have Kent M256 full race cam.
