stage v nitro heads

anyone over there already used stg V heads (nitro heads) on alky engines...? how far those heads can go with methanol only?

 

They should be fine. My Stage 5 heads are 200CC and I am not sure if all are, but you might see some performance gain if your are.

 

190CC and they look awesome.......i will try get something like 10.50 compression for only methanol and lower compression for mixed fuels......
