well its really hard to understand your post, which may be why your not getting any replys.

Im taking it you have a hotseat pipe, and matching clutch kit. (good) and you have the v force 2 reeds.

Im guessing you didn't change your main jet which you should have go up two size and check the plug color (do a search for plug chop its been discussed alot) to make sure your not lean.

as for the head you can get the stock head cut to 12 to one compression for under 50.00 to use 92 octane fuel. The hotseat head is nice but most of what you gain is cosmetics, the ability to adjust the compression ratio by changing domes, and increased cooling.

Hotseat has a foum on here you may want to post there and a hotseat tech should anwser your questions.

 

Thank you inf. I will go to check on hot seat forums. Thank

 

go for the head if you can afford them,if you ever wanna known,
i have a 14.1 dome set hot seat head that is collecting dust,
the hot seat head are better cauze of the bettwer cooling capabilities they offer and higher comp. dome ratio using premium gas.
as for wiseco is a great item to have done to it too,be sure the cylinder clearances is ok for that type of piston tough,

 

I not need one 14.1 dome head. I want one 12.1 dome head is better than 14.1 dome head. If you can tell me 12.1 dome and 14.1 dome both are same gas octane 92? If gas same octane will buy 14.1. If not same octane go to get 12.1 dome head.

 

I find out about 14.1 dome head only race gas, 12.1 dome head gas super octane at 92. I will get one buy a new 12.1 dome head soon time. 12.1 dome head help much power bottom end mid end than stock head?
