Replacement heads on Stocker
 
Does anyone think that shortly/soon NHRA will open up and allow after market heads in stock. Some of these heads are getting very hard to find and also very expensive.

I don't know protocol but I'm sure reaching out to NHRA about your concerns may be a good start.

I believe they are listed in the Stock Car Classification Guide under your Car/Motor combo. Best to check with your Divisional tech director before spending $$$ confirm HP penalties.

STK. 6380.

They are listed on some combo (not mine) BUT, if you start looking at spec's of replacement vs oem head, most replacements have a larger volume which might not be legal (unless there's a rule I don't know about).
