new head needed

[delboy71]

hi guys im new to the forum and the world of petrol power rc..i recently purchased a second hand baja 5b ss with a few mods already fitted,while i
was stripping down and giving the car a good clean i have found out one of the exhaust port holes has had the thread stripped.
so my question is what head/cylinder would be a decent upgrade without spending silly money? dont know if this would help with the dicision but it has
a jetpro v3 exhaust fitted.

thanks in advance for any suggestions.

just tap the hole to 6mm use a bigger bolt or helicoil it

You may struggle to helicoil it . But when this happened to mine i just tapped it out to a 6 mm thread

+1 on the above , or if your not confidant in carrying out the repair ,send the head to me and I'll repair the head

thanks for the replies guys,i will take the engine out and drill it out at work and re tap it to 6mm. looks like i will have to drill the holes out in the exhaust too because i dont think a 6mm bolt will go through there either..any recomendations for getting a bit more power from this fuelie 26s?

Stick a 29.5 head kit on it mate, im running a stock 26cc with a 29.5 head and it is pretty quick, it lifts the front up on throttle in wet mud anyway!!
